add support for opencl and cuda nvcomp

[alexmannen]

Is your feature request related to a problem? Please describe. i hope compression will be supported on gpu to compress vram on the fly

https://www.blosc.org/pages/blosc-in-depth/ for example this compression method have new functions to take advantage of resize bar SAM using instructions in the 36mb l2

https://gpuopen.com/brotli-g-sdk-announce/ amd and google already have support for gdeflate and gpu compression

they take advantage of the 100+ cores, i assume all the large batch textures and shaders would be perfect for mass compression.
