CESM configurations on Gadi using CIME

I’ve also kluged together a CICE6-WW3-DOCN-DATM-DROF CESM executable. Payu config can be found at GitHub - dougiesquire/d_jra_wd: Kluged-together CESM CICE6-WW3-DOCN-DATM-DROF-SLND-SGLC build scripts and payu configuration.

Same warning as above, but even more so since this configuration doesn’t even exist as a compset in CIME.
