Saturn - UCI chess enegine  Author: Egormoroz

Rating Chess Engines Diary CEDR=3386

v.1.3:

STC tests suggest the expected CCRL 40/15 elo of about 3360

Much smaller net for sick nps gains: (4x768->512)x2 -> 1

Search tweaks and parameter tuning

Compressed net weights embedded in the exe

A bit of refactoring and bug fixing (self play is still bugged though)
