Why is this PR needed?

CI on macos-latest (now a Silicon runner) fails with error: subprocess-exited-with-error when installing scikit-image, when installing pytables (presumably) because HDF5 libraries are missing.

What does this PR do?

• For the M1 CI, brew installs HDF5 libraries and adds them to the path.
• Ensures tests are run on Silicon and non-Silicon macs.
