This PR aims to update the dataprocessing module to its new version. We remade the dataprocessing module, so there are some big changes. The changes are:

• raimitigations/dataprocessing/: this folder contains the new version of the dataprocessing module. We excluded the old files and added new ones
• notebooks/: replaced all the notebooks in notebooks/dataprocessing/ by the new notebooks. I also updated the data_balance_e2e.ipynb notebook so that it uses the new dataprocessing module instead of the old one
• docs/: updated the docs of the dataprocessing module
• test/dataprocessing/: replaced all of the old tests for the dataprocessing module with the tests for the new version of this module. We currently have a test coverage of 94%
• .github/workflows/: I just made a small change to the release-pypi.yml file so that it runs the pytest for both folders in the test/ folder (previously, it was running the tests just for the test/databalanceanalysis/ folder)
• setuptools config: I updated the setuptools configurations (requirements, setup.py, setup.cfg, etc.)
• .gitignore: I added a few extra lines to the gitignore file

To install the raimitigations library, just do the following:

1. Go to the projects main folder

2. conda create --name rai python=3.8 ---- I tried with python 3.7 and 3.9 as well, and all three versions worked fine

3. conda activate rai

4. python3 -m pip install -e .
