Establish basic guidelines for coding and formatting

See https://github.com/smiley/steamapi/pull/61

Their doesn't appear to be any sort of guidelines for the code base which leads to some confusing formatting as seen in the pull above.

I would suggest standardizing in some way.

Going with Pep8 is an easy choice and is often well integrated into many editors.

Honestly after reviewing blacks code styling, I'd argue it's superior to autopep8 and I'll likely be switching my own editor to that :P
