- Trying to optimize (still)
- Known issue: sometimes the legals are not right !

Trying to optimize the MCTS performances and to reuse the tree each time

- Trying to make the reuse of the tree, instead of starting from a new tree each time, we rather update the tree starting from the layer corresponding to the new grid we got.
- Various additions to the code base

Note: this is absolutely not working

This will be ran on a VPS, results are coming later.

- Also added the __last_player to get the last player to have done an action on the grid

Implémentation des algorithmes minmax avec élagage alpha beta et mémoïsation. Pas de test car je n'arrive pas à lancer le programme.

- Added the hashing for the grid using xxhash
- Added requirements.txt
- Added a little strategy module
