Remove hachoir from MAT.

This (huge) commit removes completely hachoir from MAT.
Audio files are now processed with mutagen, and images
with exiftool, since the main python imaging library (PIL)
isn't super-great to deal with metadata (and damaged/non-standard
files).

Package maintainer should change the dependencies to reflect this.
