Walkthrough & initial simplification for Shannon

[Olshansk]

This was a collaboration between @RawthiL and @Olshansk to go through the notebooks and understand how the repo can be simplified into an initial version that can go to production.

See pokt-network/poktroll#708 for reference.

Added a missing function and pushed the executed versions of notebooks/Random_scenarios.ipynb and notebooks/Tokenomics_Compare.ipynb. There are differences to MINTv2 and Shane's model, but those are in line with what's expected after removing some functionalities to simplify the TLM module.
