Re-open Generalized Hyperbolic Stretch

[Desmis]

I accidentally merged the PR GHS #7210
I reverted with the PR 7250

I open this new PR... same code

@Desmis there is an anomaly when using GHS with a DCP (Color Management > Input Profile >Custom). To reproduce:

-Open an image and apply a DCP .
-Check the DCP parameter boxes ("Tone curve", "Look table", etc.)
-Create a RT-Spot (either Normal, Full Image or Global).
-Select the GHS tool and activate the "Stretch factor" slider
-Toggle any one of the checked DCP parameter boxes on and off repeatedly.

The image will become progressively brighter. The only way to reset the image to its original state is to click on the Camera Standard Input Profile and then reselect the DCP profile.
EDIT: See also issue #7147

This bug which was reported in July 2024, in the "apseimprov" branch has been addressed in the corresponding PR. DCP had interference with Abstract Profile.

I changed the "events" in refreshmap.cc", for DCP events

What have we been waiting for for several months, the last exchange is on September 9th, for the PR 7111 ?
I added some modifications following small bugs found by me, or improvements in visualization of SE wavelets changes. I'm not going to reopen a new PR on the same subject.
