Generate preview images

This is a utility package that allows you to find HTML files in a directory and programmatically take screenshots of them. This is intended mainly for static site generators to generate preview images for social media. Files are served using a static express server, the screenshots are taken through a headless Chrome instance using Puppeteer.

WARNING: Work in Progress. This is an unstable alpha release. Not all options are implemented yet.
