Can you update PYPI with the License for python-geohash #39

Heya - it looks like doesnt have a license set in PyPI:
https://pypi.org/project/python-geohash/

Can you update it please?
Note that python-geohash is a dependecy for Apache Superset so for some folks to use it the license needs to be set as well.

Thanks for all you contributions!
