feat(PiGear): Official Support for Picamera2 API (Fixes #342) [PR #392]

🚀 This massive update brings official support for the new Picamera2 API, unlocking powerful features for Raspberry Pi Camera Modules and limited USB camera support. ### ✨Key PiGear Enhancements include: - **Seamless Python wrapper:** A robust wrapper around Picamera2 API library simplifies integration with minimal code changes for existing PiGear users. - **Enhanced camera control:** Leverages libcamera API under the hood for Raspberry Pi Camera Modules. - **Existing compatibility:** Maintains compatibility with PiGear's existing super-charged multi-threaded and colorspace manipulation framework. - **Proper Resource management:** Ensures proper resource release during PiGear termination. - **USB camera support (limited):** Provides basic functionality for USB webcams. PiGear could accurately differentiates between USB and Raspberry Pi cameras using metadata. - **Backward compatibility:** Seamlessly switches to the legacy Picamera library backend if Picamera2 is unavailable. - **Standalone functionalities:** Standalone functionalities for both legacy `picamera` and newer `picamera2` backends for clarity. - **Document Overhaul:** * - **Advanced optional parameters handling:** Handles camera configurational parameters and user-defined settings for various camera types. - **New optional configurationalparameters:** Currently Supports "sensor", "format", "controls", "transform", "stride", "buffer_count", and "queue" with sanity checks. Seperated Raspberry Pi camera module exclusive and Unified USB cameras supported optional parameters. - **New user-defined optional parameters:** Such as `auto_align_output_config`, `enable_verbose_logs`, and more. - **Additional changes:** * Logging optimization with warning for common libcamera messages * Lowered `framerate` minimum value to `0.0`. * Moved `sensor` optional parameter to commonly supported picamera2 configurational parameters. * Removed unsupported `bit_depth` optional parameters * Updated PiGear API tagline and introduction * Fixed colorspace typo bug * Fixed UnboundLocalError bug for 'picamera2' variable assigment. * Fixed UnboundLocalError bug for 'queue' variable assignment. ### 📝 Documentation updates: * Added a warning advising users to disable common `libcamera` messages when logging is disabled. * Updated Zenodo badge and BibTeX entry * Added complete Picamera2 library installation instructions for `pip` and from source as a dependency. * Updated Picamera2 installation instructions _(including `apt`, `pip`, pre-installation on Raspberry Pi images, and compatibility warnings)_ * Moved legacy Picamera library installation instructions to an admonition. * Removed Importing section from overview to avoid confusion in PiGear. * Overhauled mkdocs theme. * Added `unrecognized_links: ignore` to `mkdocs.yml` for validations. * Added new `features` to mkdocs.yml * Added custom admonition icons to mkdocs.yml * Migrated to new Google Analytics 4 in mkdocs.yml * Added new `git-authors` plugin in mkdocs.yml * Added new tables markdown extension * Added custom fences to `pymdownx.superfences` markdown extension * Added `line_spans: __span` and `pygments_lang_class: true` parameters to `pymdownx.highlight` markdown extension * Added `normalize_issue_symbols: true` to `pymdownx.magiclink` markdown extension * Added new mkdocs feature dependency mkdocs-git-authors-plugin * Replaced depreciated `materialx `with supported emoji extension. * Replaced permalink icon with default one * Added missing version contributors to `changelog.md` * Added new icons to make headings more readable * Replaced unsupported admonitions with supported ones * Removed all custom admonition icons and color CSS from `custom.css` * Removed Twitter section from help and docs site metadata * Fixed Ko-fi sponsorship heart hover effect in footer * Replaced `twemoji` heart emoji with `heart-pulse` fontawesome SVG * Fixed titles and indentations in various admonitions. * Removed Gitter community chat sidecard JS file. * Redefined spacing between sections * Fixed various typos, code comments, and hyperlinks URLs. ### 🧑‍💻 Maintenance Updates: * Moved logging enablement before version logging for consistency in vidgear APIs. * Removed redundant boolean assignment for various APIs internal logging. * Simplified conditional statements and assignments using short-circuiting, Boolean operations, and ternary operators. * Refactored return data handling in netgear_async.py * Refactored vidgear code to improve readability, maintainability, and performance * Added `.cache` directory to `.gitignore` * Updated vidgear library version to `v0.3.3` * Dropped legacy picamera dependency in Setup.py * Improved code efficiency with short-circuiting and formatting * Updated logging practices to be more developer-friendly * Updated code highlighting in NetGear_Async Docs * Added patch for substring index bug in `get_supported_demuxers` helper method. * Updated code comments ### 👷CI Updates: * Temporarily removed PiGear API from code coverage due to hardware limitations * Fixed `pip install` hash bug in Azure Pipelines CI.

-PiGear provides a flexible multi-threaded framework around complete [picamera](https://picamera.readthedocs.io/en/release-1.13/index.html) python library, and provide us the ability to exploit almost all of its parameters like `brightness, saturation, sensor_mode, iso, exposure, etc.` effortlessly. Furthermore, PiGear also supports multiple camera modules, such as in the case of Raspberry-Pi Compute Module IO boards.
+PiGear implements a seamless and robust wrapper around the [picamera2][picamera2] python library, simplifying integration with minimal code changes and ensuring a smooth transition for developers already familiar with the Picamera2 API. PiGear leverages the `libcamera` API under the hood with multi-threading, providing high-performance :fire:, enhanced control and functionality for Raspberry Pi camera modules. 
+
+PiGear handles common configuration parameters and non-standard settings for various camera types, simplifying the integration process. PiGear currently supports PiCamera2 API parameters such as `sensor`, `controls`, `transform`, and `format` etc., with internal type and sanity checks for robust performance.
+
+While primarily focused on Raspberry Pi camera modules, PiGear also provides **basic functionality for USB webcams** only with Picamera2 API, along with the ability to accurately differentiate between USB and Raspberry Pi cameras using metadata. 
+
+PiGear seamlessly switches to the legacy [picamera][picamera] library if the `picamera2` library is unavailable, ensuring seamless backward compatibility. For this, PiGear also provides a flexible multi-threaded framework around complete `picamera` API, allowing developers to effortlessly exploit a wide range of parameters, such as `brightness`, `saturation`, `sensor_mode`, `iso`, `exposure`, and more. 
+
+Furthermore, PiGear supports the use of multiple camera modules, including those found on Raspberry Pi Compute Module IO boards and USB cameras _(only with Picamera2 API)_.
 
 Best of all, PiGear contains **Threaded Internal Timer** - that silently keeps active track of any frozen-threads/hardware-failures and exit safely, if any does occur. That means that if you're running PiGear API in your script and someone accidentally pulls the Camera-Module cable out, instead of going into possible kernel panic, API will exit safely to save resources.
