When the visitor is used by a parser, this is called to parse a move in standard algebraic notation.

You can override the default implementation to work around specific quirks of your input format.

Deprecated since version 1.1: This method is very limited, because it is only called on moves that the parser recognizes in the first place. Instead of adding workarounds here, please report common quirks so that they can be handled for everyone.
