isCheck incorrectly detects castling

Line 88 in 7bb8796

var attackFilter = (move: Move) => move.to.file === kingSquare.file && move.to.rank === kingSquare.rank;

fix on my branch is:

    boardState.moves.filter((move) => {
        if (move.isWhite === checkWhite) return false;
        return kingSquare && move.to.file === kingSquare.file && move.to.rank === kingSquare.rank;
    });
