Dominant Color support (#1569)
* Dominant Color and Mean Color Squared

* Workaround - Suppress empty LED updates

* Add missing text

* Dominant Colors advanced

* Test with fixed initial colors

* Test with fixed initial colors

* Support new processing values via API

* ImageToLED - Add reduced pixel processing, make dominant color advanced configurable

* Updates on Grabber fps setting

* ImageToLedMap - Remove maptype and update test

* Update dynamic cluster array allocation
