Review metgenc NetCDF & CSV readers and unify their configuration for the operators

Sample data set needed
Acceptance criteria:

If we ingest CSV we can still generate UMM-G

Likely same as issue 108

Acceptance criteria and sizing discussion needed

[eigenbeam]

Regardless of input data type, the operator can specify parameters that will read values from the collection metadata and granule data to generate the UMM-G & CNM.

The configuration parameters should allow the operator to use consistent configuration parameter names & values independent of the input granule file type (e.g., NetCDF, CSV) & data types (granule geometry in lat/lon or UTM or ...)

This is a 1SP strategy story -> create follow up stories for implementation
