Unsure why download function has been overwritten / called twice?
Potential oversight?

Have tested, works perfectly for me.
As was running on windows had to make a few changes to get it to run ( that i had made previously but had to do a few other changes also to make it run on windows correctly.
New PR made for this at #204
contains this PR changes aswell as windows related changes and windows pytest actions.

I would recommend removing aws cli section of readme like i did on my PR if mine doesn't get merged

I've had a deeper look at the version tagging implementation.
Automatic versioning now should work across Windows and Mac:

• Added using setuptools_scm for this feature
• Added some build config in a new pyproject.toml file

Further work that may be needed:

• Major/ Minor releases may need to have it's own branch created manually, as this automatically updates the fix/hotfix version. I'm having another look at this

great - i was able to create a new env, install dependencies and use the libraries core functionality with no errors. Looks like all tests on ubuntu and windows passed as well.
