Subject: Update default net to nn-04cf2b4ed1da.nnue

Update default net to nn-04cf2b4ed1da.nnue

Further tune the net parameters, now the last but one layer (32x32).
To limit the number of parameters optimized, the network layer was
decomposed using SVD, and the singular values were treated
as parameters and tuned.
