While hardcoding the compression to zipfile.ZIP_DEFLATED works for
most use cases of mat, being able to produce cleaned up uncompressed
zip files is useful for content that cannot be compressed more.
In addition it also enables to use mat2 for reproducible builds of
Android bootanimation files file that don't support compression.

Rework the dependencies definition to include a 'required' flags, which
is passed by the check_dependencies helper to the callers, so that they
can distinguish between required and optional dependencies.
This help in two ways:
- The unit test for the dependencies was now failing when an optional
one was missing, due to a previous rework.
- Mat2's --check-dependencies was referring to "required dependencies"
and was misleading for the user as some of them could be optional.

Remove the try/except logic when calling check_dependencies, as it
cannot throw the exception anymore (it's caught already in the
function).

- 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.
`/usr/bin/python3` -> `/usr/bin/env python3`
It's always better to trust the environment defined path to bin/python, as
virtualenv become the way to go.
