Add option to archive songs

[Amunak]

I have tons and tons of songs, some of which I don't play, but I don't really want to remove them permanently (especially as some are not available publicly anymore).

It would be amazing if one could in both local song lists (as in, in the song list and in playlists) mark songs as "archived". That could move them to a separate tab (next to Online and Local) called Archive, where they'd just sit... "backed up", but not visible by the game.

The easiest implementation would probably be an extra folder in Beat Saber Data, called something like BeatList Archive, where you'd just move the archived folders.

Thank you for considering this feature.
