Would it be possible to add a stubfile?

Hey all,

I've started using typing in python and have managed to get literally all my packages working with pylint, with the exception of jsonpickle.

Any chance we could get a stub file included?

Sure! I'm backlogged on school work at the moment, so if you can submit a PR with a stub file then I'd be happy to merge it, but otherwise I probably won't be able to make one myself for a few weeks or more :(
