ACES 2.0 planning

Remi - finding some differences between the CTL and the Nuke versions, but making progress towards the CPU implementation in OCIO. Has a prototype for SDR and working now on HDR. Slower than ACES 1 - 8x slower right now. Will optimise of course, but don't expect the same level of performance. Using C++ 14 features currently - hoping we will bump that to the minimum for OCIO 2.4. Currently planning to add a fixed function for initial things, with possibility to add more. There's an AP1 clamp that should definitely be optional.
Kevin and Scott are working on harmonizing versions etc between CTL + Python + Nuke/Blink
Remi will open a draft PR as soon as he's ready, at least with the CPU version, so folks can similarly test off one thing
There are a few things that might be worth extracting from the built-ins and refactoring for easier access from the API - matrix generation from chromaticities etc

- Lots to follow in this issue, please contribute here as more people than OCIO folks are involved.
- Please have a think about this before the next OCIO TSC, would be good to have a preferred naming/methodology from the OCIO TSC as a whole before the next color interop forum on the 17th.

Dev Days planning - Sept 26-27, 2024

OCIO is planning to participate, with the knowledge that it will run up against our deadline for the 2.4 release on Oct 1.
Carol is going to submit the project registration form, and then more work can be done on "good first issues" later on.
