[Refactor]: CDAT Migration Phase - performance benchmark

[tomvothecoder]

Is your feature request related to a problem?

• Check baseline performance of run script against main
  • Need to update zppy wall time if needed
• Explore Dask with Xarray chunking in the future for more performance gains -- might not be possible because e3sm_diags uses its own Dask multiprocessing scheduler for parallelization, and we call .load(scheduler="sync") to load Xarray Dataset objects into memory which converts dask.array to numpy.array
