An iterator over planar pixels. Models HomogeneousColorBaseConcept, PixelIteratorConcept, HomogeneousPixelBasedConcept, MemoryBasedIteratorConcept, HasDynamicXStepTypeConcept.
Planar pixels have channel data that is not consecutive in memory. To abstract this we use classes to represent references and pointers to planar pixels.

Copy constructor and operator= from pointers to compatible planar pixels or planar pixel references. That allow constructs like pointer = &value or pointer = &reference Since we should not override operator& that's the best we can do.

For some reason operator[] provided by iterator_facade returns a custom class that is convertible to reference We require our own reference because it is registered in iterator_traits
