Dominant Swatch is missing in iOS library

[Ankish]

Dominant swatch is the most important part to extract the colors. Any possible support for this ?

Android version:
/**
* Returns the dominant swatch from the palette.
*
*

The dominant swatch is defined as the swatch with the greatest population (frequency)
* within the palette.

*/
@nullable
public Swatch getDominantSwatch() {
return mDominantSwatch;
}
