Additional feature added

[BryanSJamesDev]

To add an extra major feature to the provided code, I implemented the functionality to determine if a player is in a stalemate position. Stalemate occurs when a player is not in check but has no legal moves available. This results in a draw.

I added the stalemate method to the Board class. It takes the color parameter to determine the player for whom we want to check for a stalemate. The method first checks if the player is not in check. If not, it iterates over all the pieces of the given color and their valid moves. For each valid move, it temporarily makes the move on a copy of the board and checks if the player is still not in check. If any move leads to a position where the player is not in check, the method returns False, indicating that the player is not in a stalemate position. If no such move is found, the method returns True, indicating a stalemate.

You can call the stalemate method on an instance of the Board class to check for stalemate for a particular player's turn. For example:
board = Board(8, 8)

Make moves on the board...

is_stalemate = board.stalemate("w")
if is_stalemate:
print("Stalemate!")
else:
print("Not in stalemate.")
This feature enhances the functionality of the code by allowing it to detect and handle stalemate positions during gameplay.
