Wheel support for linux aarch64

[odidev]

Summary
Installing argon2-cffi on aarch64 via pip using command "pip3 install argon2-cffi" tries to build wheel from source code

Problem description
argon2-cffi doesn't have wheel for aarch64 on PyPI repository. So, while installing argon2-cffi via pip on aarch64, pip builds wheel for same resulting in it takes more time to install argon2-cffi. Making wheel available for aarch64 will benefit aarch64 users by minimizing argon2-cffi installation time.

Expected Output
Pip should be able to download argon2-cffi wheel from PyPI repository rather than building it from source code.

@argon2-cffi-team, please let me know if I can help you building wheel/uploading to PyPI repository. I am curious to make argon2-cffi wheel available for aarch64. It will be a great opportunity for me to work with you.

Are there any CIs available that provide AArch64 VMs? There's also https://www.piwheels.org/project/argon2-cffi/ could theirs wheels be somehow reused or something?

This is fixed by the outsourcing to https://github.com/hynek/argon2-cffi-bindings

Feel free to try to pip-install argon2-cffi-bindings and report back if it's still broken.
