Correctly Serialize Maps

Happy to open a PR on this myself, want to clear with maintainers:

Map objects are not displaying any key-value pair contents. For example, our Redux store actually contains a very large Map object with a lot of data, but none of it shows up here:

Whereas when we console.log the data it does in fact serialize correctly and display. I would be happy to open a PR on this and write the serializer myself – this makes Redux dev tools much less useful when I use the Map object.

Turns out that there is an option to enable serializing non-JSON objects (serializing Maps is not enabled by default). See the serialize option (set options to true) in order to enable serializing Maps for the Redux DevTools extension.

Let me know if that works for you. Closing for now as I believe this is resolved.

@rob2d It is true that the former maintainer of this project has moved on (see https://github.com/reduxjs/redux-devtools/issues/502). Up until this past week I’ve been too busy to dedicate any time to this, but starting last week I now have quite a bit of free time for the foreseeable future and hope to be an active maintainer for this project. I’ve just started to get familiar with the code in this library and am working on multiple PRs at the moment.

All the write privileges for this repo and corresponding packages have been given to @timdorr, but I also understand that he is quite busy. Hopefully he has enough time to review/merge my PRs and publish them somewhat frequently. If that ends up falling through then I’ll end up forking the project and releasing the packages under a different name, but that would be unfortunate and hopefully unnecessary.

Regarding correctly serializing Maps and Sets in the Redux DevTools: @erezcohen said they used to work in the past. If that’s true, then there’s probably already a system in place to serialize and deserialize them correctly, and there just happens to be a bug or something else got messed up. As I become acquainted with the code, I’ll see if I run across any code that is already meant to handle Maps and Sets and take it from there.
