CraftyWinboardAVX2-25.2.2

Crafty 25.2.2 this utilizes the AVX2 instruction set. for Modern PC's.
This is a Winboard Protocol only version until I can get UCI working, a Winboard adapter is needed on some chess GUI.
Also there may be issues with 'crafty.rc' file. Currently tested as working with "arena chess GUI".
Its actually slower on older machines. That use POPCNT.

WHY? Then. Because AVX2 is FAR more compatible with many more machines. And holds many more advantages and will outperform with modern CPU's. Also I will be adding more features to the engine to take advantage of this instruction set. They just don't exist yet.
