Adapting nnue-pytorch's binary position format for Lichess

@jaxu said in #20:

The occupancy bitboard is only 1 bit per square, so it's read in row-major order. How would you know where the kings are just from the piece section?

Aahh, I misunderstood here. You're right, that will make no sense.

Board logic unleashed for the masses.....I should have said. (just re-read, search for Revoof wisdom backward, in trying to understand human chess wise all the move-chess oriented automatic chess tools.).

seeking dev terminology keys to navitagate all sorts of dev speak around perf. found a lead: symbolic. but again it is either results in the results dev speak language needs in other chess engine dev speaking purposes, or the dev speak of how it is working.

trying to narrow my hunt for the FEN data set I can use for my human chess experience in wrong chess land... (where chess logic still applies.. that obscure region of chess where no position might be encounterable in expected play, could it be still study matter and generalization skill training, appropriately).

so not here my search continues..
