Add feature yt-dlp to support yt-dlp

[luqmanishere]

This commit adds support for json emitted from yt-dlp, which is only
slightly different from youtube-dl. The changes are gated behind the
yt-dlp feature.

Youtube-dl recently broke again with ytdl-org/youtube-dl#30363 . Since this crate supports specifying youtube-dl's binary name, yt-dlp can be used as an alternative with these changes

Looks good, thanks!

This doesn't build for me

Works if you do cargo check --no-default-features --features yt-dlp
