What problem does your feature request solve?

Currently CSET does not have a facility to import Nimrod radar observations.

Describe the solution you'd like

Nimrod radar observations to be ingested into CSET. The radar observations will match the date and time scope of the model data to evaluate. The CSET GUI will be used to specify options related to the radar data e.g. where to find the data and which radar product to use.
