Exceptions for invalid moves

The logic raises exceptions for:

  • Invalid pawn moves, including out-of-board and illegal jumping events (exceptions.InvalidMove)
  • Invalid fence placements, including out-of-board fences, overlapping fences, and fences that block unique pawn paths (exceptions.InvalidFence)
  • Moves after game is over (exceptions.GameOver)
