adding --netcdf4 option to ESMF_Regrid (option already available using CLT ESMF_RegridWeightGen)

[jvmcgovern]

Hi there,

I recently identified an issue where when I was interpolating to a large output netcdf, the .log file would indicate that I never got the line "Finalizing ESMF".

Is it possible to add netcdf4 capability to the ESMF_Regrid CLT options as with ESMF_RegridWeightGen?

Best regards
