Docs/sim notebook refactor

[jason-bentley]

This PR

This PR adds a refactored simulated data-based FACET classification tutorial that explores the following:

1. The impact of correlation/interaction between features and how synergy and redundancy changes
2. How synergy/redundancy change with max_depth in a random forest

Note that because the simulations take some time, the data used for the results presented have been added to the tutorials folder, so when documentation is rebuilt, we do not need to wait for simulations and ensure we always can regenerate the exact same figures.

To run
Navigate to the sphinx folder and run python make.py html.

Expected outputs
Examples of the expected output are below.
