Subject: [PATCH] minimp3: remove TAG+ support

It's a still-born extension that no one uses, no player
supports, and no tag library parses.

And it's not impossible to hit it as a false positive..

(The removal has already been suggested to mainstream at
https://github.com/lieff/minimp3/issues/66)

(cherry picked from commit f9933b5bdafb8b0d2b5fb9e28523b37c76a6863c)
