Python 3.10 Support

[sbaer]

We need to start building a binary distribution for Python 3.10

[fraguada]

Added python 310 to

• workflow_ci build_py_all_bdist matrix
• workflow_release build_py_all_bdist matrix

Testing builds now on workflow_ci seems to work ok. Anywhere else we need to add 3.10?

@sbaer check the artifacts of this workflow run: https://github.com/mcneel/rhino3dm/actions/runs/1461953321 There should be python 3.10 releases for linux, macos, and windows.

The Python 3.10 packages work great. Tested on MacOS and Windows.
