Wheel support for linux aarch64

[odidev]

Summary
Installing scandir on aarch64 via pip using command "pip3 install scandir" tries to build wheel from source code.

Problem description
scandir doesn't have wheel for aarch64 on PyPI repository. So, while installing scandir via pip on aarch64, pip builds wheel for same resulting in it takes more time to install scandir. Making wheel available for aarch64 will benefit aarch64 users by minimizing scandir installation time.

Expected Output
Pip should be able to download scandir wheel from PyPI repository rather than building it from source code.

@scandir-team, please let me know if I can help you building wheel/uploading to PyPI repository. I am curious to make scandir wheel available for aarch64. It will be a great opportunity for me to work with you.

@odidev Sorry for not replying initially! Just doing some issue cleanup/replies. Can we do this with a GitHub Workflow hook or similar? I'm not sure best practices or tools at this point, as I've been out of the Python loop for a while.
