The OpenEXR format has a chromaticities attribute that identifies the scene referred linear color space. Detect these two cases now, and assign the corresponding color space from the OpenColorIO configuration. In general these chromaticities are known to be unreliable and missing support in most software, with ideas to deprecate them entirely. However the ACES container format standard requires them, and with this change we'll be able to read such images with the right color space set by default.
