Description of your issue or question

When using file_regrid.py to create a GCHP restart file from a GCClassic restart file, the dry pressure variable is created using the wrong name (DELPDRY). The correct name should be DELP_DRY.

To reproduce :

$ python -m gcpy.file_regrid --filein GEOSChem.Restart.20190101_0000z.nc4 \
       --dim_format_in classic \
       --fileout GEOSChem.Restart.20190101_0000z.c24.nc4 \
       --cs_res_out 24 \
       --dim_format_out checkpoint
$ ncdump -cts GEOSChem.Restart.20190101_0000z.c24.nc4 | grep "DELP"

Output:

        float DELPDRY(time, lev, lat, lon) ;
                DELPDRY:_FillValue = NaNf ;
                DELPDRY:long_name = "Delta-pressure across grid box (dry air)" ;
                DELPDRY:units = "hPa" ;
                DELPDRY:averaging_method = "instantaneous" ;
                DELPDRY:_Storage = "chunked" ;
                DELPDRY:_ChunkSizes = 1, 72, 144, 24 ;
                DELPDRY:_Endianness = "little" ;

This causes benchmark plotting jobs (i.e. budget_ox.py) to fail, since the plotting code is looking for the wrong name.

I will make a PR with a fix.

PR #297 is now merged into dev, so we can close this issue.
