Homebrew package on macOS

It would be much easier to install this using homebrew to avoid polluting my day to day system python, it would be walled off over in homebrew. Then I could stop worrying and just brew install gitsome and brew upgrade gitsome and move on with life. I shouldn't need a hypervisor to run a simple command line program.

If I have time I might write the formula myself, this is just a chance for someone else to beat me to it.
