Add macOS aarch64 wheel

[TylerADavis]

I am trying to install a TF Nightly wheel that I built from source, and it seems that TensorFlow requires libclang>=9.0.1. However, there is not an aarch64 or universal2 macOS wheel available for download on pypi, so my pip install is failing.

I see in #11 that there is now a Linux wheel, and it would be great to have one for macOS as well. I'd be glad to help out, but I'm not sure what generating the new wheel would require.

Steps taken:

❯ python3.9 -m venv ~/tensorflow_blank_39
❯ source ~/tensorflow_blank_39/bin/activate
❯ pip3 install --upgrade pip numpy wheel

I have upload the macos arm64 wheel to pypi:

https://pypi.org/project/libclang/12.0.0/#files

I remember that I have tried in #7 but it is rejected by pypi at that time. Now it is available.

Thanks for bringing this issue out!

Thanks! It installed without issue using pip.
