v2.3 frame flags are incorrectly described

[Bart Massey]

Sadly and bizarrely, the frame flag bits were shuffled around randomly between id3v2.3 and id3v2.4. As a result, idiii reports the flag bits incorrectly for the frames of an id3v2.3 tag.

OK, here's a patch. It's kind of kludgy, and I'm not very proud of it. Better would be to have the frame parser return the flags as a set by semantic, rather than tuples of booleans. The latter format is obviously pretty error-prone and inextensible. The former format would allow not passing the ID3 major version redundantly in the flags types.

My branch of idiii pushed here contains my patch above.
