[Python] Suggestion: Support Python 3

[OllyNuralAND]

Firstly, thank you for a fantastic library to use for uploading packages to AEM! I'm using it currently in our CI/CD process and it is working fantastically.

However I am currently having to use Python2 for all our python scripts due to errors I see when trying to run with Python3. Is there any planned work to support for Python3, especially as Python2 EoL is coming up in a year or so?

Thanks!
