Update NNUE architecture to SFNNv19 and net nn-d1ee674a62ca.nnue Building upon K32Q2 (#7215), add a third block for when no heavy pieces (Queen, Rook) are left. The new K32H3 layout is generalized to be block-major, with each block occupying contiguous space in the network. This should allow for further net pruning and facilitate future arch changes. Separately, the threat input/pawn pair horizontal mirroring schemes are flipped to match the HalfKA orientation.
