Navidrome/subsonic jukebox mode

[RainbowPants]

What do you want to be added?

I'm interested in using feishin as a dekstop navidrome library browser where I can use my home server that hosts navidrome as the actual playback device. it's implemented using subsonic api so it's not server-specific.

I'm also interested in this feature. I can help test it if needed
