Add CPU emulation

[JayFoxRox]

I think this should also support CPU emulation / patching, so it can avoid (illegally) sharing copyrighted material or derivatives thereof (Asm and Cpp submodules).

CPU emulation could be based on Unicorn-Engine (most platforms), or a virtualization provider like KVM, HAXM, WHPX, HVF (or an API to those, like https://github.com/StrikerX3/virt86).

This will also require some fix for #48 and #49.
