New version chess engine: Pingu 3.0.0

Pingu - UCI compatible chess engine built from scratch.

Author: William Ching Rating CEDR=2697

v.3.0.0:

I am pleased to announce the release of Pingu 3.0.0!

This version of Pingu has an estimated strength of ~2800 elo relative to CCRL Blitz.

The most significant improvement was the introduction of NNUE which has replaced Pingu's HCE. A short write-up of the process can be found in Pingu/docs/nnue.md. Other changes can be found below and also in the full changelog.

N.B. the provided binary requires a CPU with AVX2 instruction set.

Late move pruning: at low remaining search depth, prune the node after a set number of moves

Reverse futility pruning: fail high if static evaluation exceeds beta by a depth-dependent margin

Ordering captures: order winning captures by MVV/LVA instead of by SEE scores

Evaluation

Implement NNUE: train network using Pingu 2.0.0 self-play data and fully replace HCE
