yt-dlp migration (scdl v3.0.0)

[7x11x13]

This PR turns scdl into a yt-dlp wrapper so it is easier to maintain in the long run (and probably also fixes a lot of the current bugs). I tried to provide as much backward-compatibility as possible by patching yt-dlp and submitting PRs upstream. Feedback is welcome.

Added

• --yt-dlp-args <argstring> to allow passing of yt-dlp args as a string (using yt-dlp CLI format)

Fixed

• Make --sync method work as intended

Changed

• Use yt-dlp to download and process tracks
• Store description in "comment" tag instead of "description" tag for Ogg/FLAC files
• Change default track format string to include track artist and ID
• Drop termcolor, requests, tqdm, pathvalidate, filelock dependencies
• Switch to pyproject.toml instead of setup.py
• Breaking: Change --sync file format to include downloaded filenames

Removed

• Breaking: Remove --remove
• Breaking: Remove -n
• Breaking: Drop support for Python 3.7 and 3.8
• Breaking: When writing to stdout, files no longer contain metadata
