Add type stubs for all distributed modules.

[CruzR]

Hi, I've implemented one of the solutions for adding type hints I discussed in #24. Would be nice if you could have a look and decide whether this seems acceptable to you.

I don't hate the idea :)

I tried it out built with your change merged and nothing much seemed to happen when I run mypy -m noise. Is this mostly useful for dependent programs using noise?

Also I notice there's a test.pyi included. That one seems a bit useless :)

I was just looking around for noise stubs and found this MR. Yes, the type stubs are for dependent programs, so that we can check that we are calling noise functions with the correct types.

@caseman can you merge this and release, please? 😄
