The original idea here was that NNUE is best with a slightly different tempo value to classical, since its style of play is slightly different. It turns out that the best tempo for NNUE varies with strength of play, so a formula is used which gives about 19 for STC and 24 for LTC under current fishtest settings.

It also simplifies emptySquares instantiation. In addition, I added a comment in generate_moves() to clarify Check branches.
