Saturation & Brightness/Value Gain using Oklab color space (#1477)

Browse Source 
* Imported Oklab reference implementation

* Add Okhsv conversions

* Fixed formatting error

* Add saturation and value gain to schemas

* Add english translation for saturation, value gain

* Created OkhsvTransform

* Make OkhsvTransform configurable

* Apply OkhvsTransform

* Clamped values during transform

* Precalculate isIdentity in OkhsvTransform

* Skip OkhsvTransform if it is the identity function

* Added changelog message

* Allow for full desaturation

* Imported recommended changes by LordGrey

* Fixed typo in constant

* Fixed anti-pattern in ok_color.h

* Correct indentions

* Correct remote-control

* Limited maximum gain settings to practical range

* Renane valueGain to brightnessGain for clarity and understanding
