Allow to use with `elm-verify-examples`

[Flavio Corpa]

Many author's seem to rely on elm-verify-examples to ship their Elm packages, would be nice to support this library as well to be installed by elm-tooling if it is possible? 🙏🏻

Hi! elm-verify-examples is written Node.js, and tools written in Node.js are not supported:

…written in Node.js and uses other npm packages. You can’t beat npm (or other Node.js package managers) when it comes to installing npm packages.

So Node.js based tools are not supported. Only tools that are distributed as platform specific executables are.
