Merging into redux-devtools monorepo

[zalmoxisus]

@kachkaev what do you think of merging this package and redux-devtools-chart-monitor to monorepo as discussed in reduxjs/redux-devtools#412 and romseguy/d3tooltip/issues/1? I already merged d3tooltip and map2tree. Also created related issues there. If you want to maintain it as a separate repository, that's ok.

@romseguy granted me npm access, so we can use the same packages. The problem is that we wouldn't want to keep orphaned/archived repositories in the org, so after merging to the monorepo we should probably transfer these two repositories back to @romseguy. Sorry that I wasn't active when the discussion about moving to the org started.

Hi @zalmoxisus! I'm totally fine with moving this repo into a monorepo. Feel free to revoke npm access from me if that's required 😉

Thanks @kachkaev! No reasons to revoke access. Added you as a collaborator toredux-devtools repository.

I'll review #17, then move it to monorepo.
