Description

### What problem does your feature request solve?

Currently we can only plot a single transect per model variable, with one set of start and end coordinates. It would be nice to plot multiple, to get a look at how they vary throughout the domain.

### Describe the solution you'd like

Some kind of list of start and end points that we can then cycle over? Maybe something like the field definition?

### Describe alternatives you've considered

Currently you can just run CSET multiple times to achieve this. It would be nice to do it in one shot.

Research direction

Start by tracing the existing single-transect configuration and plotting entry point, then compare it with the field-definition approach suggested in the issue. Define how multiple start/end coordinate pairs are represented and cycled within one CSET run, and verify that one run produces the expected transect plots across the domain.
