Please update the PyPI for MoverScore

[zakhan4]

Hi,

Thanks a lot for this awesome work. I saw that there are some new functionalities in the library for example, the ability to use another model instead of DistilBert model. But the PyPi for this implementation has not been updated since April 9th 2020: https://pypi.org/project/moverscore/. Can you please put the latest code in a new version in the existing PyPi for MoverScore?

Thanks!
