NPM builds are missing files in dist directory

[drpepper]

Hello, I just tried installing this project, and my build environment can't find several files referenced in the package.json.

Indeed, both of these seem to be missing from dist:

  "main": "./dist/maquette-advanced-projector.cjs.js",
  "browser": "./dist/maquette-advanced-projector.umd.js",

PS: You can see the files in the NPM package here: https://www.npmjs.com/package/maquette-advanced-projector?activeTab=code
