🚀 Python-nocodb is getting bigger so time for adding more tests and ci to it 🙌🏻

This was something that I've made for myself at the beginning but as it seems that is being used by a lot of people we need to make sure that everything works like a charm.

I'm creating this issue to self-assign some tasks although help is always welcome.

Tasks to be done:

- [ ] Add more tests.
- [ ] Add black to format the project.
- [ ] Automate black, mypy and tests in ci.
- [ ] Improve docs. It would be great to have a webpage instead of a README that its getting bigger and bigger.
