Commit ID c079acc26f93acc2eda08c7218c60559854f52f0

Update NNUE architecture to SFNNv5. Update network to nn-3c0aa92af1da.nnue. Architecture changes: Duplicated activation after the 1024->15 layer with squared crelu (so 15->15*2). As proposed by vondele. Trainer changes: Added bias to L1 factorization, which was previously missing (no measurable improvement but at least neutral in principle) For retraining linearly reduce lambda parameter from 1.0 at epoch 0 to 0.75 at epoch 800. reduce max_skipping_rate from 15 to 10 (compared to vondele's outstanding PR) Note: This network was trained with a ~0.8% error in quantization regarding the newly added activation function. This will be fixed in the released trainer version. Expect a trainer PR tomorrow. Note: The inference implementation cuts a corner to merge results from two activation functions. This could possibly be resolved nicer in the future. AVX2 implementation likely not necessary, but NEON is missing.
