I created an engine, that uses a basic version of the minimax algorithm
to evaluate a position.
It then evaluates all the possible next moves in a given position and picks
the one that has the best evaluation.
Basic test cases were also added.
Moved was a 10x12 1-d array, that stored bools.
It was only used for checking if a pawn moved (especially important for
the double move of the pawns) and if the other pieces moved (important
for checking if the player can castle or not).
The pawn moves are now checked by the starting position (pawns on the
second rank cant be already moved).
The castle rights of a game are expressed as CastleRights, a tuple with 4 bools.
This saves basically 116 boolean values.
