Description

As an alternative to the single-point, "middle of the largest connected component", we can add an option to use the median of all high coherence points.
This can be taken from https://github.com/opera-adt/opera-utils/blob/main/src/opera_utils/disp/_reference.py#L79-L81 (minus the xarray implementation)

Research direction

Start by reading opera_utils/src/opera_utils/disp/_reference.py around lines 79-81 to understand the high-coherence median reference behavior. Then locate Dolphin’s current single-point reference option and determine where the new option belongs, excluding the xarray implementation; done means users can select the median of all high-coherence points.
