OpenEXR and Radiance RGBE

[ajz3d]

Hello,

Any chance of adding support for OpenEXR and Radiance RGBE (.hdr) image formats?
I believe that both formats are handled by libopenimageio. I understand that adding additional package requirement might not be desired, so to speak, but these two image formats (especially OpenEXR; Radiance much less) are rather important in VFX and GameDev pipelines, so it would be quite convenient to have them readable by feh.
