Filter out Xing/LAME info frames, rather than letting them go to the mp3 decoder as if they were audio frames. Fixes the 1152-sample zero pad at start of some decoded mp3 files (distinct from decoder delay). The logic here is based on the madplay code.

# a bit much to expect everyone to have JAMS installed just for

# (e.g. it doesn't seem to work correctly with Python 3 at the moment)
# so let's not make this fatal either.
