Build wheels for Python 3.9

[Gowee]

Hi!

cibuildwheel is ready for Python 3.9 (pypa/cibuildwheel#440 ). Also, I have tested cryptg on Python 3.9 where it builds well. It would be great if cryptg can provide with prebuilt wheels for Python 3.9.

Thanks.

Update on this, Linux and macOS builds are now available (https://pypi.org/project/cryptg/0.2.post2/#files), but we're having trouble with the Windows build (https://ci.appveyor.com/project/cher-nov/cryptg/builds/36088966):

This is actually already fixed in cibuildwheel 1.6.4 after being noted in pypa/cibuildwheel#452, pypa/cibuildwheel#456 and maybe partially pypa/cibuildwheel#443. But for some reason the AppVeyor still downloads the pretty old version of it (1.1.0), as it can be seen from the build log. Trying to investigate that now.

Seems to be done now. Please test.
