Fiddler Everywhere traffic inspector

[maxgolov]

Our 1DS C++ SDK provides a "Classic" Fiddler inspector. Unfortunately the "Classic" Fiddler is a .NET Framework app that runs nicely on Windows.. But barely runs on Mac, esp. since it uses Mono, AND it used to use 32-bit Mono - Fiddler app doesn't work too well on Catalina (as in Mr Stark, I don't feel so good...) , that now supports 64-bit apps only. This is a bit of an issue. Even when Fiddler worked on Mac, the experience was rather glitchy.

Now there's a new initiative - "Fiddler Everywhere", https://docs.telerik.com/fiddler-everywhere/user-guide/live-traffic/inspector-types , which does not seem to be like a C# app, but more like a Javascript (Electron?) app. Due to unrelated circumstances I did some prior work on writing a WebAsembly (thus, Node and Javascript)-compatible protocol decoder in this PR: #336

Proposal:

• take the prior art and transform it into ready-to-use node.js and javascript module / library
• plug-in that library as "Fiddler Everywhere" inspector

Benefit is that we may enable engineers running on Mac and Linux to use an outside generic traffic inspection tool, with an opensource decoder implementation available in our repo.
