React native windows support

[JadedBlueEyes]

Support for the react-native windows platform.

See:
https://microsoft.github.io/react-native-windows/docs/native-modules

We probably only care about the new C++ target, as opposed to the C++/WinRT target, as this is the focus of new development for react-native-windows.

Sample project here

In the long term, we are very open to supporting react-native-windows and react-native-macos with this project -- generated bindings for Rust makes a lot of sense as a cross platform solution.

At the moment our current dev focus is on adding support for a wasm32 target (to support react-native-web), but we always welcome collaborations and contributions. We would probably need some help from someone who knows the react-native-windows ecosystem if we were to ever take this on, since it is not part of our teams core strength.

Hi @JadedBlueEyes !

This is really interesting, especially the sample project.

I'm not at all familiar with React Native on Windows, so am not the right person to do this work. However the concepts you need to know for you to do it are described in this doc.

As @zzorba said, we haven't got a lot of bandwidth right now, but I'd be happy to provide reviews and documentation for you to do it. What do you think?

Hey @jhugman, that's absolutely fair.

Thanks for the docs link and the review offer! Right now I'm pretty busy, but I should have some free time over Christmas. I probably know even less than you, but I'll give it a shot haha. I'll be in the Matrix channel in the mean time!
