Add requirements.txt

[Reckless-Satoshi]

We should add a requirements.txt on the root directory so it is easy to get an environment running with all of the required libraries.

Example requirements.txt

matplotlib==3.7.1
numpy==1.22.0
pandas==2.0.0
seaborn==0.12.2

Then we just need to run pip install requirements.txt to get started
