    audio: Fetch ASIN with libsoup instead of libmusicbrainz
    
    We are only using libmusicbrainz for finding the ASIN code for a
    given artist and album.
    
    With this changes we use libsoup to query the musicbrainz API
    directly, allowing for the dependency on libmusicbrainz5 to be
    dropped.
    
    See https://musicbrainz.org/doc/MusicBrainz_API
    and https://musicbrainz.org/doc/ASIN
