Light cover support

What

Add the album cover thumbnail in the header while playing music.

How

• Get cover from musicmetadata for file formats supporting it (picture : [ { format : 'jpg', data : <Buffer> } ],)
• Define how to store it: create a file ? Link the file to the track with a collection ?
• Get a “no-cover” fallback image
• Front-end

musicmetadata gives you a cover in base64 or sth (so it uses the file metadata, it’s not the most accurate, but I pref that instead of an online search).

BUT, a button in the admin “fetch covers online and update my files metadata” could be a really great feature. I’m keeping that in mind.

I’ll see if I can do something about the UX and UI for the cover.
