Make the Discography library switcher toggle All/In Library/Not in Library

Problem: Although we have library badges to denote library titles in Discography, these are small and pretty hard to parse on the album cover.

Solution: Adapt the Library toggle switch to work three ways so it goes All > In Library > Not in Library in a similar vein to the old focus switches that went from blue to red when toggling an exclusion filter.


Would be a great feature. The badge is to small if you have many albums


+1 (Would appreciate it!)
