Night Nurse 0.3 is coming along

[dkappe]

Scores have inflated a bit, and it’s not completely helpless vs sf12 anymore. Both running 1+1 on the same sf12 executable.

The latest net, a long time in coming. 1.5x scaling looks about right, so the hard coded 1.25x of sf12 seems to work ok. NiNu-0.3 at 1.5x looks to be about 40 elo better than Ninu-0.2 at 2.5x. Enjoy.

Thanks, Dietrich! Nurse's still a great attacker, judging by the game you posted.

An argument against the ‘all NNUE engines play the same’ crowd. Here a fun one, 60+1 on the same sf12 executable.
