this is for gimp exported EXR

example usage from

https://openimageio.readthedocs.io/en/latest/oiiotool.html

wow, so oiiotool in itself a bit like imagemagick :)

might make preparing some image sequences easier ...


also, guess we better to note in manual that even if cingg outputs fp32
exr/tiff values there are normalized to 0-1.0f as far as we can see.
