Fix AcoustID false rejections for tracks with featured artists in square brackets

AcoustID sometimes returns featuring info in square brackets like [W/ Barnes Blvd.] instead of parentheses. The       normalizer only stripped parenthetical featuring tags, so these tracks failed verification and got quarantined despite being   correct. Now strips [W/ ...], [with ...], [feat. ...], and [ft. ...] bracket patterns too.
