Adding python types

[sbdchd]

Thanks for the project, it's been super useful!

I was wondering if you'd be open to adding types to the repo to support https://www.python.org/dev/peps/pep-0561/#packaging-type-information

Hi @sbdchd,

I'm absolutely willing to merge contributions that make our type annotations compatible.

The problem with this library is that it was using type annotations before PEP 561 was written. We are using them in the code, but in a non-compliant way. There's quite a bit that needs to be fixed in order to be compatible, but unfortunately I don't have the bandwidth myself. If you or anyone else wants to work on this, please go ahead ;)
