Mypy reports "Module 'rx' has no attribute 'Observable'" since 3.1.1

I don't know what has changed, but after I updated to RxPy 3.1.1, mypy began to report such errors as "Module 'rx' has no attribute 'Observable'", possibly due to python/mypy/issues/7423.

It happens for all other major types such as BehaviorSubject, and changing [mypy] implicit_reexport in setup.cfg to True fixes the symptom.

I guess this is related to #524, for fixing #515. Before 3.1.1, rx was maybe silently unsupported by mypy in your project?

@jcafhe I think what you suggested could be entirely possible since my project is just two weeks old, so it didn't have too much code before 3.1.1.

This should be fixed in the latest --pre release and will be fixed in the next major release
