Add support for Windows

[dstaley]

With React Native for Windows becoming a viable target, enabling this package for Windows would be a great benefit to the community! (Especially if this package backs uuid, since a library I plan on using in RN uses it.)

I'm willing to take a stab at an initial implementation, and wanted to post this issue as a place to track progress.

Todo:

• Ensure RN for Windows supports synchronous methods It does!
• Decide if C++ or C# would be the most appropriate C# would be the most approachable, and would be just as performant as the C++ version since they're both just calling UWP APIs
• Determine if RN prefers Win32, UWP, or both for third party modules RN for Windows only works on Windows 10, so there's no sense in using the Win32 APIs.
• Setup project (blocked by Unable to add Microsoft.ReactNative to native module project microsoft/react-native-windows#4211)
• Rewrite module in C++ (blocked by Unable to activate Windows Store app after adding C++ native module microsoft/react-native-windows#4215)

Is there any update to this? I think there has been a resolution in those referenced issues.

Definitely adding a +1 to this. Any updates? The blocks on the final step appear to have been resolved.

It would be great to see progress on this issue.

Does look like #15 does try to address this.
