Martin-Vignali f7054a2d2f OpenEXR: Automatically set colorspace for XYZ E and ACES2065-1 chromaticities
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.
