Summary

📝🎨🚀

This pull request introduces a new _Logger class that handles all the output and warning functionality of the YoutubeDL class, and refactors the existing code to use it. It also adds some helper functions to redirect the warnings module and set the return code based on the error messages. The changes affect the yt_dlp/YoutubeDL.py, yt_dlp/output/helper.py, and yt_dlp/output/logger.py files.

To improve the logging and warning
The YoutubeDL class was reforming
It now uses a _Logger
With colors and VT toggler
And some functions for output conforming

Walkthrough

• Refactor the logging and warning functionality of YoutubeDL by using a _Logger instance from the output.logger module (link, link, link, link, link)
• Add the redirect_warnings and _wrap_download_retcode functions to the output.helper module, which are used to redirect the messages from the warnings module to the _Logger instance, and to set the return code of the YoutubeDL instance based on the error messages, respectively (link)
• Add the _Logger class to the output.logger module, which encapsulates the logic for handling the output files, color policies, VT mode, bidirectional workaround, and logging and warning messages. It also defines the _Styles namespace, which contains the color codes for different types of messages (link)
• Make the tb and is_error arguments of the trouble method of the YoutubeDL class keyword-only, to avoid confusion and errors when calling the method with positional arguments (link)
• Remove the unused imports and attributes from YoutubeDL.py (link, link, link, link, link, link)
