Windows support added while maintaining MacOS/Linux compatibility

[dan-dean]

Changes to package.json and inclusion of run-script-os in dev dependencies so that users on MacOS/Linux and users on Windows run different scripts. Added go-compile-windows.sh which builds the binary exe for windows. Modified the README with Windows specific setup steps. I do not have a MacOS or full Linux environment, so you should try my fork on your environment first for compatibility, but hopefully this should do it.

I want to merge this but it's a big PR that will require a lot of testing on multiple platforms. If someone can help test this out and write up a testing document with all of the results, I would be happy to merge! Thanks @dan-dean for the awesome work on Windows compatibility.
