Replacing iterative solve for gamut hull calculation?

[KevinJW]

Can we invent a direct hull calculation rather than solve iteratively solve as this will help with performance and inversion.

[KevinJW]

Plot gamut hulls as a set of points and try fit a minimum volume ellipsoid and see if there is close enough fit.

There's also Björn's gamut approximation. I used it in OkishDRT.

As part of the discussion on 11/01/23 Alex and Pekka offered to try some different approaches for parts of the problem hopping to show something at the next meeting.

[KevinJW]

In this weeks meeting we had two demonstrations showing how the gamut hull could be approximated as well as an exploration of the point raised https://community.acescentral.com/t/aces-2-0-cam-drt-development/4700/112

Whilst the visualisation tools helped further work is needed to better understand the overall "flow" of the movement caused by the gamut mapping and how the true hull interacts with the various stages of the whole mapping.

This was done in v030.
