Unable to add songs/albums from artists that use custom domain URLs with Bandcamp

There are some artists that use custom domains with Bandcamp where it will redirect any URL's for that artist to their custom domain and thus stripping out the bandcamp.com domain. There appears to be a check to verify that the web URL contains bandcamp.com and it will prevent a URL from being added if it doesn't contain bandcamp.com https://github.com/impliedchaos/mopidy-bandcamp/blob/8a6c8586e5f99c82909dba6bdcac622cdc258ff1/mopidy_bandcamp/web.py#L13 For example, if you try to add any music from Monstercat, you'll receive an "Invalid URL" error message. Example URL: https://music.monstercat.com/track/move-back  Here is the documentation on how artists can setup custom domains for their music along with it notating that any bandcamp.com address will automatically redirect to their custom domain. https://get.bandcamp.help/hc/en-us/articles/360007902973-How-do-I-set-up-a-custom-domain-on-Bandcamp-
