Zangdar - UCI chess engine (written in C++11).

v.3.04 NNUE:
I finally entered the NNUE world. With a big increase in strength.
The first network was simple (768->128)x2->1, and was created with the last version of Zangdar, still HCE.
After that, I made a second network (768->256)x2->1, with an intermediate version of Zangdar using the first network.
I generate for that 600 millions fens, and used Bullet as a trainer.
Zangdar can also use SIMD instructions for AVX2 processors. Unfortunately, I don't have a AVX512 computer, so I can't
give binaries for that.
The classic evaluation and the tuner have been removed, as they don't have any use now.
There are also some corrections here and there, the usual.
I give only binaries for AVX2, BMI2, and native; the old architecture are too old.
