Add linting to CI

[jgadling]

1. Add linting to CI to fail the build if code doesn't pass typical python lint checks. Typically pre-commit does a pretty good job of allowing linters, type checkers, etc to be configured in a standard way (example here -- https://github.com/chanzuckerberg/cryoet-data-portal-backend/blob/main/.pre-commit-config.yaml)
2. Run code formatting tools on the repo so that it passes lint checks.
