Wheel support for linux aarch64/x86

[odidev]

Summary
Installing retrying on aarch64/x86 via pip using command "pip3 install retrying" tries to build wheel from source code

Problem description
retrying doesn't have wheel for aarch64/x86 on PyPI repository. So, while installing retrying via pip on aarch64/x86 machine, pip builds the source code resulting in it takes more time to install retrying. Making wheel available for aarch64/x86 will benefit aarch64/x86 users by minimizing retrying installation time. We can release the wheel using CI/CD tools such as travis-ci, circle-ci, azure-pipelne etc..

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

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