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

I'd like to be able to see whether I've liked the currently playing track. Right now I have to press a and observe whether the option shows AddToLiked or DeleteFromLiked.

Describe the solution you'd like

Add {liked} as a formatting option for the playback_format configuration option. This option would insert liked_icon when the track is liked. It would update when liking/unliking the track.

Describe alternatives you've considered
