NNTC PBR material set compressor: now supports CPU encoding

Developer Rich Geldreich's NNTC (Non-Neural Texture Compression) PBR material set compressor now supports CPU encoding in addition to CUDA, with encoding and viewing also tested on Windows ARM. The project already supports VK_NV_cooperative_vector, with D3D12 Linear Algebra remaining as the major outstanding item, and an updated prior art disclosure dated Sept. 19, 2026 has been published.
