Python object: ``phenotypic.schema._size.SIZE``

Measure colony area and integrated intensity as lightweight size proxies.

Extract two fundamental size metrics per detected colony: pixel area
(biomass extent) and integrated grayscale intensity (total brightness,
a proxy for optical density). This is a convenience class for rapid
size assessment without the overhead of full shape or intensity
statistical analysis.
