TypeScript files with Sarif Object declarations

[joshbw]

It would be quite useful to have a couple TypeScript files with the Sarif objects declared. That would make working with Sarif output super easy to script in Node.js, and selfishly, would save me some time adding Sarif output support in DevSkim

Thanks for the input, Josh! Tell me your thoughts on this. We have a SARIF SDK for .NET (https://github.com/Microsoft/sarif-sdk) with C# class declarations for the SARIF objects. So similarly, I suspect what we'd want here is a SARIF SDK for Node.js.

@michaelcfanning FYI for your thoughts as well.
