The [Radiance RGBE](https://en.wikipedia.org/wiki/RGBE_image_format) (``.HDR``) format is commonly used as a texture source file format in game development for high-dynamic range images, but this format is not supported by any built-in WIC codec. These functions implement a simple reader and writer for this format.
