Patch the Greenland snow hole with initial conditions for ne30 and tweak the C14 isotope latitudes Point to tweaked C14 Isotope file so that the latitude line is straight and regrid doesn't change depending on processor count. Also bring in a new ne30 finidat (Initial Conditions or IC) file so that the Greenland snow hole won't exist in ne30 initial conditions.
Introduce CRUJRA2024b datm option (Greenland snow hole filled) - Includes corresponding changes in cdeps by updating cdeps1.0.84 to cdeps1.0.91; for consistency with cdeps, I also updated cmeps from cmeps1.1.24 to cmeps1.1.29 - Includes renaming of CRUJRA2024 files present in /python/ctsm/test/testinputs/expected_result_files to permit all tests to pass The default datm input dataset changes from CRUJRA2024 to CRUJRA2024b. The former has Antarctica filled and the latter has Greenland also filled. User may select either CRUJRA2024 or CRUJRA2024b using long compset names, e.g. HIST_DATM%CRUJRA2024_SLND_SICE_SOCN_SROF_SGLC_SWAV_SESP HIST_DATM%CRUJRA2024b_SLND_SICE_SOCN_SROF_SGLC_SWAV_SESP Answers Change: New climate over Greenland due to the new datm files; cpl output diffs due to the submodule updates listed below.

Description of changes
cdeps1.0.92 will be merged and tagged soon from cdeps PR ESCOMP/CDEPS#375.
Specific notes
Contributors other than yourself, if any:
CTSM Issues Fixed (include github issue #):
Fixes #3386
Are answers expected to change (and if so in what way)?
No, because cmip6 co2 is still the default.
I will follow this PR with another pair of PRs (cdeps ctsm) where default co2 changes from cmip6 to cmip7.
Any User Interface Changes (namelist or namelist defaults changes)?
The new dataset (cmip7) spans 1750-2022 instead of 1750-2014.
Also, co2tseries.20tr got split into the two options co2tseries.cmip6_20tr and co2tseries.cmip7_20tr.
Does this create a need to change or add documentation? Did you do so?
Testing performed, if any:
While working on the cdeps PR, I ran aux_clm successfully once:
