Add targeting support for .NET Standard

[jimmyheaddon]

Something like this potentially, so that the NuGet package can be imported in .NET Standard projects?

That'd be immensely useful!

I noticed that the current prerelease 1.0.0 beta has netstandard support... unfortunately, it has that as a dependency when you attempt to install it in a .NET framework package as well, which creates many dependencies that I assume wouldn't be necessary in a project targeting .NET framework. I would imagine that a .NET framework 4.5-4.6 application would still only need Newtonsoft.JSON
