SSE4.2 support

Thanks for the great work with box64! Is there any estimated timeline on when we might see support for SSE4.2?

I see you responded here https://boilingsteam.com/box64-witness-the-birth-of-the-arm-gaming-scene/ about a year ago:

The emulated x86_64 CPU has all the minimum expected extensions: FPU/MMX/SSE/SSE2. Also SSSE3. I started a few SSE4.x opcodes, but it is not fully supported yet.

Is that still in progress?

there is partial SSE4.2 support, but it's not complete, and not in my immediate todo. Some 4.2 opcodes are really complex, What do you need SSE4.2 support for?

With https://github.com/ptitSeb/box64/commit/5c13f8f10ac82ca642a6c930585989cc0d75a664 I have added SSE 4.2 support
