Fix failing CI tests (ffmpeg on apple silicon, PySide2 problems) (nap…

…ari#222)

In this PR:
1. `brew install ffmpeg` for Apple Silicon Mac arm64 runners on github
actions, since imageio-ffmpeg does not provide ffmpeg binaries for Apple
Silicon imageio/imageio-ffmpeg#71
2. Restrict PySide tests to Mac Intel (not Apple Silicon), and for all
operating systems python>=3.10. PySide is not available for these
configurations.
3. Drop python 3.8, and add python 3.12 to the CI test matrix
