[Enhancement] Synced Lyrics support via LRCLIB

[Readf0x]

I've been using th-ch/youtube-music for streaming for a while now, and they (at some point) added support for live/synced lyrics using the LRCLIB API. I think this would be a great addition to dopamine!

You could potentially also allow for providing your own lyric files (maybe by looking for a txt, or some other extension, plaintext file with the same name as the song).

For reference, here's the LRCLIB API docs.

Quick & dirty mockup:

@Readf0x Thanks a lot for the tip! Look like a cool feature to add indeed :) By the way, Dopamine already looks for a text file containing lyrics. The file must be in the same directory as the song file and must have the same name as the song file, but with extension .lrc instead. Currently Dopamine supports unsynced lyrics for lrc files but synced lyrics is planned.

I love synced lyrics in dopamine 2, it really adds something to listening to music.

Just as an idea, it might be cool to have the current lyrics line in place of the audio visualizer.

Also an option to automatically save (cache) lrc files while playing.
