[feature] move item in playlist

[ghenry22]

How can we move an item in the playlist without disrupting the playback? Playlist re-ordering is a a pretty core feature for most music players.

If moved from after currentTrack to before currentTrack then the index of currentTrack will change (+1)

If moved from before currentTrack to after currentTrack then the index of currentTrack will change (-1).

If moved from before to before no change to index of currentTrack

If moved from after to after no change to index of currentTrack

Can the currentTrack be moved in the playlist while status is playing?

i think we would need an API and implementations for all platform, but that sounds like a nice extension, if you could start a MR i think that could be accomplished soon
