[hgangwar]

• Adds the $\text{dimVar}$ in $\text{RCBPtn}$ read/write functions.
• Fixes the $\text{cutsVar}$ scheduling.

@hgangwar Would you mind pushing another very simple commit (i.e., add a non-offensive empty line somewhere in redev.cpp) so that our CI triggers again? This is the first commit to this repo in a very long time and github automatically disabled the build+test workflow. Nevermind. There is something wrong with that workflow (see https://github.com/SCOREC/redev/actions/runs/18237925126/job/51934949032).

The workflow is not up to date with the current CMakeLists.txt. Perfstubs was introduced later and is now a required package.

adios2 vendors perfstubs ... even in the ancient version 2.9 that we are using. An issue for the CI problem is here: #50

[cwsmith]

@hgangwar Would you please merge or rebase on main? There are changes there to the CI that should fix the adios/perfstubs issues with the latest failing CI builds.

@cwsmith looks like this is all set to merge.
