Github Issue: #173

Description

Spatial dimensions were being added to pressure variables thus the pressure variable was being bloated.

Overview of work done

Subset variables that have the dimensions in the indexers array in xarray_enhancements.py. Variables that do not have those dimensions should then be merged after xarray.where function applied.

Overview of verification done

Testing that the variable dimensions are the same going in as going out.

Overview of integration done

Explain how this change was integration tested. Provide screenshots or logs if appropriate. An example of this would be a local Harmony deployment.
