Subsonic API support

Is your feature request related to a problem? Please describe.

Describe the solution you'd like

Subsonic API, such as the one used in Jellyfin/Gonic/Navidrome should be supported for listening to music.

Would be cool on PSVita as there is no good network audio client.

Describe alternatives you've considered

ElevenMPV-A, but it doesn't support this.

I really love to see this, In my phone I prefer using navidrome server as my music provider instead of jellyfin as it provides more and accurate metadata compare to the available metadata providers on jellyfin, specially on artist image.

But I think it will defeat the purpose of the "Switchfin" being a client for "Jellyfin" server but I hope, but its up to the dev wether he add it or not, still happy with the app
