add gsw_xarray to MDTF_python3_base conda environment? #799
Description
What problem will this feature solve?
gsw_xarray is a wrapper that allows the gsw package (TEOS-10 seawater equation of state) to work with xarray objects. Using it rather than non-xarray gsw would make our POD more robust.
Describe the solution you'd like
Add gsw_xarray to the MDTF_python3_base environment
Describe alternatives you've considered
Using gsw without xarray objects would be possible, but less robust.
Additional context
Working with @TeaganKing on this part of the POD implementation.
