Backend updates (0.3.0)

ℹ️ An update to the core codebase to bring it more in-line with recent releases.

⚠️ Note: The documentation is a little out of date visually. But functionally the asset hasn't changed. This will be updated at some point in the future.

🗓️ Release Date: 24th May 2024

🎨 Asset Changes

- Added the latest asset core systems such as version validation, asset indexing, better editor utils etc.
- Improved the setup for a few editor bits with the asset.
- Audited the codebase to meet my 2024 standards where possible without breaking functionality for now, further audits to come.
- Updated readme for package.
