Enhancement: SeriesAnalysis - make netcdf python package optional #3255

@georgemccabe

Description

@georgemccabe

Currently the SeriesAnalysis wrapper will fail to run if the python netCDF4 package is not available. This package is only used when generating plots via the wrapper to compute min/max values. This could be made optional so the package does not prevent SeriesAnalysis from running when it is missing.

Describe the Enhancement

Move import of netCDF4 package to the min/max function and have the function log a warning message and return None, None if the package cannot be imported.
