[Feature proposal] Support Blob, File and FileList

[BrainCrumbz]

Hi there.

We're using Chrome Redux Dev-Tools Extension (for Angular NgRx apps, actually).

Within an app state at some point we also have a JS Blob and a File objects. Those are always shown as {} in State panel, so even when they change they do not show up at all in the Diff panel. Or at least that's our understanding.

companyLogo: {
  main: {
    current: {
      imageBlob: {}
    ...

From this gaeron answer we got that probably the core of the thing could be here in react-json-tree. And looking at this code that might as well be.

Would you consider a PR trying to extend support to some of those JS types? Of course we could reason about how to best show them, and how to work within code.

Kind regards
