Local adjustments - Log encoding - addition of ciecam processes (#5973)

Browse Source 
* First LA log encoding ciecam

* Some changes hide show and tooltip

* Change label - tooltip

* Change max slider shadow

* Fixed bad behavior cat02 adaptation in some cases

* Another fix Cat02 GUI

* LA log encode add ciecam saturation

* LA log encoding - added contrast J ciecam

* LA Log encode various changes GUI labels tooltips

* Change 2 tooltips

* Clean code
