Build wheel for Python 3.10 and Apple M1

[connorferster]

Hi @drufat!

Thank you for this excellent Triangle wrapper. We use it in sectionproperties and, by extension, concreteproperties.

Your package is quite popular and I think that, as Python 3.10 is becoming more widely adopted, it would be wonderful if you were willing to publish an update in PyPI with wheels built for all platforms with all of the latest versions of Python.

I believe that this can be done automatically through GitHub actions using this tool: https://github.com/pypa/cibuildwheel.

Thank you for taking the time to consider this request and thank you for your contributions which allow us to build great tools from your Triangle wrapper.
