Add discogs as a source for fetchart

[jordanbs]

Use case

I'm trying to use beets to fetch album art. Many of my albums have album art on discogs, but fetchart struggles to find album art with all the default sources enabled.

Example: Hiroshi Yoshimura - Soundscape 1 - Surround

fetchart: Hiroshi Yoshimura - Soundscape 1 - Surround: no art found

Solution

The art exists on discogs. Discogs integration is amazing for the autotagger! Perhaps it could work for fetchart too?

Alternatives

Finding manually and using embedart works just fine.
