Add saved sims

[mhluska]

Similar to CVCX, we can precompute the simulation results with several billion hands. It can be done with every permutation of table conditions as well as some preset table minimums ($10, $15, $25, $50, $100 etc).

There's be a storage format like JSON to serialize and commit to the repo. And maybe a CLI arg to bypass and recompute the result if needed.
