Add provenance and parents to climate ontology

[cthoyt]

This PR adds the provenance information from which system (i.e., Halfar System, Budyko Sellers) a given term was derived. Some terms are found in multiple. Note that the "part_ofs" list uses CURIEs for the systems, so for Halfar, you want to look for askem.climate:0001002

To extract the list, use:

from mira.dkg.askemo import get_askem_climate_ontology_terms


def main():
    for curie, term in get_askem_climate_ontology_terms().items():
        if "askem.climate:0001002" in term.part_ofs:
            print(curie, term.name)


if __name__ == "__main__":
    main()
