- Mixed Layer depth diagnostic code added for analyzing model output - Takes MLD_003, MLD_EN1, MLD_EN2, OR MLD_EN3 as inputs. - Creates map of input (either min or max of monthly means) - Compares to similar field from obs (usually Argo based).

@breichl - Looks really good. Mostly a few minor nits.
Major comments:
- Please apply the black code formatter to your .py files
- Consider whether or not using xESMF for regridding would work better for this diagnostic

Copying in general increases the memory footprint. You can access the underlying NumPy arrays by using the .values method, e.g.
obs_lat = ds_obs["Lat"].values

In general, there is a lot of code here to implement regridding functionality. I wonder if using xESMF would be more streamlined?

I agree xesmf should be used instead of griddata, there is a function in om4common to regrid data
