Support for Python 3.10

[yatmanov]

Can we get release for python 3.10?

This is a great tool! I am using it to include entire standard library to a single executable file since pyinstaller doesn't have this functionality. So far only this package keeps me from updating to the latest python version.

Turns out there's no need to update this package. Python 3.10 already comes with list of standard modules: https://docs.python.org/3/library/sys.html#sys.stdlib_module_names
And there's discussion on how to use it to include standard library to PyInstaller builds: pyinstaller/pyinstaller#6824

I actually wanted to look into that for a while. I do recommend you to use that but be sure to add both sys.stdlib_module_names and sys.builtin_module_names to cover everything.
