Please accept this pull request. My npm audit report looks very bad because of the ansi-html vulnerability.

@Z-Zhao Unfortunately this project seems to have remained dormant as the Ember community has shifted their focus to building out Embroider as the eventual replacement for Broccoli.

For now I would recommend specifying the updated version as an override in your package.json. Assuming you're using (a modern version of) NPM, this would be:

"overrides": {
  "ansi-html": "^0.0.8"
}

(If you're using Yarn, use "resolutions" instead of "overrides".)
