Add vae-decode-hdr node with HDR support (#2174)

Added a new custom The vae-decode-hdr repository is for a custom ComfyUI node designed to preserve High Dynamic Range (HDR) data during VAE decoding. The developer, Sumit Chatterjee, created this node to address the limitation of ComfyUI's default VAE Decode node, which compresses outputs to a 0-1 pixel range, resulting in a loss of dynamic range.

The node uses a "scientific approach" to analyze the VAE's conv_out layer and intelligently expand highlight regions, bypassing the clipping that typically occurs. The repository also includes a companion tool called the "Linear EXR Export" node, which is essential for creating professional HDR output files that are ready for use in compositing software.
