It's much better at streaming writes, which avoids the "trickling" you see sometimes when writing large files.

Description of changes
This PR contains two commits with changes I made during work on
generate_gdd20_baseline.py.The first commit touches many other files, because it standardizes the output netCDF format from our Python tools to be
NETCDF4_CLASSIC. This is compatible with CTSM while also greatly improving write performance.The second commit is much simpler: It makes an output directory if needed.
Specific notes
Contributors other than yourself, if any: None
CTSM Issues Fixed:
Are answers expected to change (and if so in what way)? No
Any User Interface Changes (namelist or namelist defaults changes)? No
Does this create a need to change or add documentation? Did you do so? No
Testing performed, if any:
Tested as part of my crop reparameterization work.
