Can we change file for "run_sample.py" from a pickle file to a more portable format?

[aramirezreyes]

When running run_sample.py on python 3.7 with:

netcdf4                   1.5.8                    pypi_0    pypi
numba                     0.55.1                   pypi_0    pypi
numpy                     1.21.6                   pypi_0    pypi
xarray                    0.20.2                   pypi_0    pypi

...PI computation complete and saved

The error occurs because the pickled file was saved with an unknown version of pickle and they are not supposed to be compatible (see e.g. pydata/xarray#5642) a better Idea could be to redistribute the file as netcdf or hdf5.

This is a good idea. I'll need to create the file that avoids compatibility issues as you suggest. Please stay tuned.

Actually now that I notice, mdr.pk1 is not used anywhere as far as I can see. It is loaded in run_sample.py but its contents are never used. That line could be removed. If there is some functionality for the basins dataset we can use netCDF (I could contribute a PR if you think this is a good idea.).
