Programmatically running a PGN string

Executing a PGN string can be done in only a few lines of code.

from pyanchetto.chess import Chess
from pyanchetto.pgn_interpreter import ChessInterpreter
from pyanchetto.pgn_parser import parse_notation
board = Chess()
interpreter = ChessInterpreter(board)
game = "1. Nc3 f5 2. e4 fxe4 3. Nxe4 Nf6 4. Nxf6+ gxf6 5. Qh5#"
tree = parse_notation(game)
interpreter.execute(tree, True)
print(board.fen())
print(board.pgn())
