Consider splitting into multiple modules

[RubenVerborgh]

webpack 4.x started giving the following warning:

WARNING in asset size limit: The following asset(s) exceed the recommended size limit (244 KiB).
This can impact web performance.
Assets:
  mashlib.min.js (1.5 MiB)

WARNING in entrypoint size limit: The following entrypoint(s) combined asset size exceeds the recommended limit (244 KiB). This can impact web performance.
Entrypoints:
  main (1.5 MiB)
      mashlib.min.js


WARNING in webpack performance recommendations:
You can limit the size of your bundles by using import() or require.ensure to lazy load some parts of your application.

We've thought about this in the past. For instance, would be great to only load the JSON-LD library when we encounter a JSON-LD document.

The drawback seems to be more moving parts, i.e., not a single .js file anymore.
