Drop-in FSR 3.1 upscaler for Direct3D 12 that runs DLSS's network (Model E) on AMD GPUs

Just tested it on CachyOS with a RDNA2 GPU on a game i ran with Optiscaler and FSR4.1.1.b beforehand. GPU times for the upscaling were halved with HelixSR in my case. Imagequality takes a small hit though(sharpness, temporal stability, smearing). But its still in a different league compared to FSR2/3. Depending on the game/hardware/performance target its a pretty nice alternative to the rather performance hungry FSR4 dlls for older AMD GPUs.
