X-FEN output #2

Closed alexobviously closed 1 year ago

https://en.wikipedia.org/wiki/X-FEN Basically use standard FEN castling notation (KQkq), unless there is an ambiguity and then use Shredder-FEN (AFaf). So this can result in strings like AQaq.

Requires determining ambiguity

Decided to cancel this because it seems like a relic that isn't really needed. At some point we will support easy custom FEN generation which would cover this anyway.
