integrate linting and code formatting tools

[rahulbot]

The central story-indexer has an implemented approach to standardizing our linting and code formatting for the broader project. We should integrate that into this code base to have things be more consistent.

I will just copy the pre-commit config from story-indexer and clean it all up in a new branch- this will be first priority, since it's the largest pain I think .

53 Will address this, pending a small lift to make mypy happy

Relatedly- project is missing a pyproject.toml, so configurations are scattered. Potentially a separate issue tbd

Merged #53, so closing.
