Adds python validation workflows

[mouse-reeve]

I'm thinking that it would be helpful to get this in place early, but I'm happy to chill if it's more of a hassle right now than it's worth. And I don't want to have Black create a bunch of conflicts with existing work

Things to fix before this is ready because I need to go to work right now:

• Make it clear how to actually run black
• Make the pylint one actually work
• Add tests workflow
• Update code formatting

Sounds good. FYI the original repo came with tox and once I worked out what that is, it seems to be useful. So I've reconfigured it to add options for black, pylint, and pytest.

I'm currently finalising linting of the tests, then tentatively this may be almost ready - so yes please don't pull this before checking with me, but I'm linting and testing everything so it should be relatively plain sailing once this first bunch of stuff is complete.

Thank you, I just realized tox is there and I haven't figured out how to get it to work with pylint but it made getting the workflow for the tests so much easier

[mouse-reeve]

Okay it looks like the workflows work! I'll just leave this until you're ready for it.

[hughrun]

Sorry just pushed up a bunch of stuff that probably has broken your model!

I moved the main code into a src directory to make it easier to package with build.

So tox commands should be:

• tox - will run pytest
• tox - will run black on everything
• tox -e pylint -- src will run pylint on the actual code
• tox -e pylint -- tests will run pylint on the tests

I'll add a CONTRIBUTING page soon to clarify.

[mouse-reeve]

No worries! I'll check back in tomorrow morning and update this to reflect where it's at.

Pylint isn't working for me locally so I'm trying to get it to pass here. I can revert the changes to the tests if it's easier to not have them in this branch

@hughrun ready to merge?
