Some obvious followups to this are to further tune this PSQT, or
try 8x8 for other pieces. As of now I don't plan on trying this
for other pieces as I think the majority of the ELO it brings is
for pawns and kings.

Looking at the new values, the differences between kingside and
queenside are quite significant. I am very hopeful that this a
llows SF to understand and plan pawn structures even better than
it already does. Cheers!
