Update nnue-architecture to SFNNv15 Updating nnue to a new architecture including a newly trained net using recipe https://github.com/vondele/nettest/pull/395 and trainer https://github.com/official-stockfish/nnue-pytorch/pull/480. The recipe contains many small improvements additionally the newly relabled data. Thus this is a combined effort.
