[API Request] Support catalog number tags in AlbumID3 response

[atj]

Type of change

API extension

Proposal description

It would be nice to support the CATALOGNUMBER tag which is set by default in at least MusicBrainz Picard and MP3tag:

$ eyeD3 example.mp3 |grep -a CATALOGNUMBER -A1
UserTextFrame: [Description: CATALOGNUMBER]
ZENDNL192
$ metaflac --list example.flac |grep CATALOGNUMBER
    comment[11]: CATALOGNUMBER=WARPDD21R

The field can be multi-valued so it would be similar to recordLabel (e.g. an array of strings).

I may be in the minority but I find this information very useful, especially now that I am able to browse my collection via record label.
