203: expose std::pin r=yoshuawuyts a=yoshuawuyts

This is important when defining / calling futures, so it makes sense for us to also export this.

But also given recent user feedback on the confusion on pinning, I'd like to open up the possibility to experiment with providing better pinning facilities  such as [`pin-project`](https://github.com/taiki-e/pin-project) or [`pin_mut`](https://docs.rs/pin-utils/0.1.0-alpha.4/pin_utils/macro.pin_mut.html) behind flags. I'm not sure if we could, or even should. But I want to allow us to have that conversation and test things out (even if it's just in floating patches.)

Thanks!
