Add development tools

[pamelafox]

• [x] black
• [ ] flake8
• [x] pre-commit
• [x] pytest

Let me know if you prefer other tools.

Poetry currently has black, isort, and pytest as dev dependencies.

I can see removing black and sort and adding pre-commit as a test in CI/CD.

[kjaymiller]

in the meantime I am going to run black+isort on this and setup pre-commit (outside of gh actions)
