This feature has always been available, just specify the network path in the engine parameter

the base size is larger - it is about 15% slower.
At the same time, there are 8 more outgoing levels, this also increases the size.

Slower but with this new nnue better than many many books. And about slowness we can adjust with Move Overhead parameter.

Sometimes change the (materialist, positional) balance

Our new nets output two values for the side to move in the last layer.
We can interpret the first value as a material evaluation of the
position, and the second one as the dynamic, positional value of the
location of pieces.

This patch changes the balance for the (materialist, positional) parts
of the score from (128, 128) to (121, 135) when the piece material is
equal between the two players, but keeps the standard (128, 128) balance
when one player is at least an exchange up.

So far, the following chess engines had added support for the new weight.

1) Corchess
2) Eman
3) Raubfisch
4) ShashChess
5) Stockfish development version

Any other chess engines oso follow suit?
