Enhance TC-RMW to reorder the dimensions of the NetCDF output to store the gridded dimensions last

[JohnHalleyGotway]

Describe the Enhancement

During development for MET #2168, it was noted that the NetCDF output generated by the TC-Diag tool should order the NetCDF output dimensions as time, lat, lon. The python diagnostics code expects the dimensions to be ordered in this way. I also see this convention in WRF files:

float UU(Time, num_metgrid_levels, south_north, west_east_stag) ;

And in SWPC NetCDF output files:

float TEC(time, latitude, longitude) ;

While the CF-convention does NOT force an order for the dimensions, the earlier COARDS convention does, as described in this section. And it is generally encouraged to considered to continue with this ordering for compatibility with existing tools, such as ncview.

This task is to reorder the dimensions of the NetCDF output from the tc_rmw tool to list the range and azimuth dimensions last. So change...
FROM: double TMP(range, azimuth, pressure, track_point) ;
TO: double TMP(track_point, pressure, range, azimuth) ;

Time Estimate

4 hours.

Thanks @bikegeek for finding the code to generate TCRMW plots in METplotpy:

Its reads in data via read_tcrmw in the tc_utils.py:

These will need to be updated.
