apparently my mac has python version 3.7.3 but github's is 3.7.7.

 * https://github.com/actions/virtual-environments/blob/master/images/macos/macos-10.15-Readme.md#language-and-runtime

I'm just going to determine these dynamically, but it should probably be able to have the user set a specific version in the SETTINGS, then the script goes and fetches that version of python. For now I just want to get *something* working before all my 10x mac minutes expire for github workflows for the month :/
