Small Refactor

[pmariglia]

Too many changes to even count, but here's the important stuff

• re-name project to Foul Play (rename repository to pmariglia/foul-play after merging)
• integrate pmariglia/poke-engine as the search engine
• support generations 1-9 (megas, z-moves, and dynamax are not supported)
• remove python engine in showdown/engine/
• a bunch of improvements that I won't even try to enumerate with the battle client in battle_modifier.py
• refactor set-prediction & randombattle sets included in source (gen9battlefactory too)
• battle-bots are now minimax and mcts
• formatter/linter as make commands
