This PR forces to use the AliceVision "ocio.config" file for all conversion between color spaces defined in the config. Previously, the conversion between sRGB and Linear was handled by OpenImageIO, without specifying an "ocio.config" file leading to an undefined behavior depending on whether the $OCIO environment variable was defined or not.
