UCI help with pawnHash key

[Mateusz]

Hi,
I'm adding UCI to ATAK and I have fixed updating pawnHash key.
You can test yours engines with this UCI command

position fen 7k/8/8/8/3p4/8/4P3/7K w - - 0 1 moves e2e4 h8g8 h1g1 g8h8 g1h1 h8g8 h1g1 g8h8 g1h1 h8g8
Does engine see draw?

Crafty apparently fixed this between 23.2 and 23.3. 23.2 seems clueless but 23.3 solves it with eval very quickly.
