Update r-dist for SLES15

[rlucches]

r_dist is used in post-processing utilities in the ops implementation of FP. The version in the tag still had a construct that worked under SLES-12, but fails under SLES-15. This has been fixed.

Hmmm. I don't think this is meant to go into GEOS-FP. You didn't change 1000 files.

From the git logs this seems to be based off of the g5.42.2 from @rtodling.

I think we need to do a couple things. First, @rtodling should tag off of this branch. But then this PR should go to main, so we get the changes into the mainline of GMAO_Shared development.

I just changed the base to be to main. Now I see four commits:

https://github.com/GEOS-ESM/GMAO_Shared/pull/381/commits

two from @rtodling and two from @rlucches

@mathomp4 the problem w/ changing the base is that GEOSadas v5.42.7 is not on main!

I changed the name of this PR to something sensible. I have no idea how changes to hermes and transf ended up in this PR. I did not change anything there. The only change I made was to r_dist and perhaps the CHANGELOG. It looks like those other changes are from Ricardo, but I am not sure how they got lumped into #381.

@rlucches The reason why the @rtodling changes are in this is because you started from g5.42.2 (which is what the ADAS was using). There are changes in that tag that are not yet in main here.

So, when you make a PR from your branch to main, it's all the changes not yet in main.

Note to @rtodling: this didn't affect the GEOSgcm probably because we don't use these codes. So, if you are happy, you can press the Merge button.

Not sure why CI is unhappy. I just pushed an update
