Closes #96

- More tests
- More documentation
- Minor code cleanup

This should improve epub compatibility,
along with other formats as a side-effect

It's not mandatory to actually have a comment inside
comment delimiter, like `/**/`.

This should close #95.

without /etc/ld.so.cache available in the sandbox, tests fail on gentoo with:
/usr/bin/ffmpeg: error while loading shared libraries: libstdc++.so.6:
    cannot open shared object file: No such file or directory

This should make easier to get more metadata from
archive-based file formats.

- This commit introduces optional dependencies (namely ffmpeg):
  mat2 will spit a warning when trying to process an .avi file
  if ffmpeg isn't installed.
- Since metadata are obtained via exiftool, this commit
  also refactors a bit our exfitool wrapper.

Since FLAC files can contain covers, it makes sense
to parse their metadata
