CI testing

I'd be nice to have the built wheels tested in CI as well.

If it's something simple like running the test.py script I'd be happy to provide a PR adding a test step/job to the GitHub Actions workflow, just need a confirmation about how to test it.

Without a HW machine with attached USB device(s) I don't see much else to test. Perhaps some USB-over-IP solution could help?
However, I'm not sure how to make that happen in secure way :D

I was mostly wondering if there were unit/integration tests good enough to run in CI. No need to connect to a device, but it'd be good to check that the libusb library is properly linked and accessible.
