Feature Request : Like on artists and albums

What is the problem you are facing?

In the actual version (0.16.1) it is possible to like songs but not artists or albums. Liking artists or albums would be nice to be able to search quickly into music you like, and have radios based on liked albums or artists.

What are the possible drawbacks or issues with the requested changes?

A bit of overhead in the database to have links between users and artists and albums but it should be less heavy than liking songs.

A bit of interface overhead to see only liked artists or liked albums. I suggest a checkbox in the artist list to only see liked artists, same in album list once it will be implemented #483 (closed).

Context

Funkwhale instances can quickly have thousands of artists and it can be hard to find music you like easily. Spotify by default only see artists you follow (which make sense considering the millions of artists they have), and I think it would be a nice improvement for funkwhale.
