Cannon Pawn Empire MirrorX

See https://blog.silverview.buzz/variants/empire . Pawns are replaced by Cannon Pawns. Soldiers do not promote. Cannon Pawns can promote to chess Queens only (as in Empire). Cannon Pawns move as a king OR they can hop over any adjacent piece to either land on a vacant square behind it (move) or if that landing square is occupied by an enemy piece, the cannon pawn will capture it by displacement.

This is a user-catalogued casual variant. Technical details such as board size, FEN, pieces, and hand rules are defined in the Fairy-Stockfish variants.ini block below.
