Setup initial CI gating on tests and add linting tests (#85)

* add flake, black, mypy, and bandit to run

* fixes issues flake and black complained about

* make mypy run successfully, add configuration files rather than specifying in ci

* respond to feedback

* configure bandit, ignore a file used only in local development
