Chess game update

Today I added the insufficient material feature. It took me a while to figure out because I was trying to use formulas and math to make the code analyze if a certain set of pieces can lead to a checkmate, but I realized that instead of calculating, I can just find which combinations of pieces cannot lead to checkmate, and then list those pieces in the code for the game to constantly check, and then determine if its a stalemate/draw.

Below is the combinations of pieces that cannot lead to a checkmate that my code checks and accounts for:

• King vs King
• King + Bishop vs King
• King + Knight vs King
• King + Bishop vs King + Bishop (same color squares)
