Loading a NNUE file.

Performance is horrible. Very roughly, for go depth 25 in starting position:

1600 knps native x86-64-sse41-popcnt
1000 knps native x86-64-sse41-popcnt nnue
1000 knps wasm master branch
10 knps wasm nnue
60 knps wasm nnue with -msimd128 (allows: sse, ssse3, sse41), requires --experimental-wasm-simd flag in Chrome

Not known where performance is lost.

@niklasf one guess, you set sse3 = yes in the Makefile, should probably be ssse3 = yes (one more s)

Oh, wow, thanks! That would have taken me forever to find. Unfortunately it didn't do much for nps.
