Leverage an external library for DXT compression in Texture Format Tests #55

Open abaire opened 2 years ago

RygsDXTc is unfortunately not a drop-in replacement as handling of the alpha channel differs. It may be better to spin out nv2a-specific DXT1 and DXT5 compressors or to do a more thorough search for more options.

In the interim, I've implemented basic DDS file loading and nvidia provides free compression utilities that can generate appropriate test files: https://developer.nvidia.com/gpu-accelerated-texture-compression
