[BandcampBridge] Update to use newer POST API (#1045)

Browse source 
Bandcamp tags pages have a new layout and now use a POST API endpoint to view each page of releases.

Output of this bridge should be almost the same as before, with a few small improvements:
- Small album image in 'content', larger album image in 'enclosures'
- RSS item titles/authors are appended with the releaser in parentheses if the artist name and the releaser are different (i.e. Record Label's Bandcamp releases an album called Bar by the band named Foo, it would get the title 'Foo - Bar (Record Label)' and the author 'Foo (Record Label)')
