Fix ColorSpace || Aces CG-config || Blender

All credit to Blender Bob and Chat GPT for creating this script that automates the color space conversion process for those people working with Aces in blender.
Here is the original video. The dropbox link is in the description.

I've only adjusted this script for the following:

1. To support the latest aces cg-config file - found here:
   https://github.com/AcademySoftwareFoundation/OpenColorIO-Config-ACES/releases
2. Support reference image conversion
