Detailed Description

Defines the atomic element of the visibility data class. This contains the visibility with various additional accoutrements. This will be passed to all objects that require a visibility data value (e.g., likelihoods) and therefore can accrete additional elements but cannot rearrange elements internally to ensure backwards compatability. Because data must never change during analysis, all elements are necessarily consts, requiring some minor gymnastics at initialization.

Within the datum_visibility class, station codes are arbitrary, but elsewhere may be assumed to correspond to either the one- or two-letter station codes identified in https://eventhorizontelescope.teamwork.com/#notebooks/97662:

List of one- and two-letter EHT station codes.
