Add github actions for CI

[Minion3665]

• When a new PR is submitted, autoformat code with autopep8 and remove
  commented out code
• After reformatting, commit back to the pull request
• When reformatted code has been committed, lint it with pycodestyle

On github side we will

• Require all changes to be submitted as PRs
• Require all CI checks to pass before merging PRs

This change partially-fixes #1 and fixes #10

@Minion3665 I have made the repo public

Looks good, not entirely sure about eradicate as it may give a false positive but I'll trust it.

You could use the command poetry install --only dev instead. This will install all dev dependencies which can then be run. Or place all linting/reformatting in its own dependency group (https://python-poetry.org/docs/master/managing-dependencies/) and use the command poetry install --only reformat-lint.

I'll take a look at using poetry.

I think even if eradicate does give an occasional false positive it isn't much of an issue as we'll still have the old commits in our history, so I'm not too worried about the chance of that happening

Don't worry too much about using poetry but add the packages used to the dev dependencies so they could be run/pre-checked before pushing.

That would be annoying to do but fair
