Basic Ci/CD and fix code style

[juanitorduz]

Partially closes #57

This PR:

• Add Makefile
• Add lint and tests requirements
• Add dummy test folder / file
• Fix style (black + flake8 + isort) of the whole code base.

@drbenvincent, please double-check the small changes I had to do to fix the style. Feel free to push changes to the branch. I tried to change the least as possible.

Note that the tests and lint are passing on my fork: https://github.com/juanitorduz/CausalPy/actions/runs/3517816662/jobs/5896022154

The lint check detected a duplicated name

/causalpy/data/simulate_data.py:101:1: F811 redefinition of unused 'generate_time_series_data' from line 70

[drbenvincent]

These are the only instances of generate_time_series_data in the repo and one of them is in the docstring, so a little confusing.

[juanitorduz]

Ok! Thanks for checking! It might be I messed up something when resolving conflicts. I'll take a look 🙈

[juanitorduz]

But in line 66 you also have a generate_time_seried_data function right? (Same name ?)

[drbenvincent]

I'm not sure what's going on. From a search I only got 2 hits. But yes, I see now. Maybe just too much coding for one day!

[drbenvincent]

Do we need to add the generated .coverage to .gitignore, or does that need to be included in the repo?

[drbenvincent]

I've checked all this over and run the pre-commit checks locally, and the various make commands. Made one commit a moment ago to fix a duplicated function definition. Everything seems fine at this point.

I think you must have merged main into this branch after my updates on Wed evening, but if you can just confirm then I can approve and we can merge.

@drbenvincent , in 5a74cd8 I added some changes which make the version setting easier. Also fixed some missing lint problems. If you see the ci/cd output now is green: https://github.com/juanitorduz/CausalPy/actions/runs/3539004142/jobs/5940424788

Please take a look into it and test locally by running make init.
