[aur-requests] [PRQ#18131] Merge Request for python-ffmpeg

[xiretza]

This is an interesting one - quoting from the official Python package
guidelines[1]:

> For Python 3 library modules, use python-[modulename].

The module itself is imported using `import ffmpeg`, however the package
on pypi is called `python-ffmpeg`[2]. Which of those is the "module name"?
