`prop-types` dependency is missing in package.json

[Finesse]

The library package requires prop-types when process.env.NODE_ENV !== 'production' and the prop-types package is not added to package.json. Therefore when I try to build my application using Webpack or Rollup, I get an error saying that the prop-types package is not found.

Version

1.3.2

Expected Behavior

The prop-types package is installed automatically or a peer dependency warning is shown when one installs the reactjs-popup package.

Actual Behavior

No warning is shown, the prop-types package is not installed and a bundling fails.
