Quiz Plugin incompatible with Reveal 4 (Offer to fix)

Reveal 4 switched from loading dependencies using the dependencies property in Reveal.initialize({...}) to using the plugins property with ES6 modules (See https://revealjs.com/plugins/#dependencies for details). This (awesome) quiz plugin is thus unusable (so far as I can tell) in Reveal 4.

My partner and I would really like to incorporate this plugin into our application - would you be amicable to a pull request fixing the issue? Thanks!!
