Interface: EncodingResultFloat

Float encoding result (no quantization). For testing and incremental encode/decode. Decode does not need to know the tone mapper: the gain map stores the ratio (HDR_linear / SDR_linear) per pixel, so decode = linearize(SDR) * gain.

Adobe/Ultra HDR spec requires SDR base to be sRGB (display-ready).
