2.8.3: Update dependencies and experimental bundle

This release is pretty much only updates to our dependencies.

The project is also now being tested using the Jest framework!
Better than the custom solution from upstream.

[EXPERIMENTAL] There's also a bundled ESM version available.

(This is a republishing of 2.8.2 but with a proper .npmignore)
