Add possibility to add/update components to the catalog on the fly.

Motivation

Lazy loading scenario, both on server and client side.

Hi @majo44,

thanks for the feedback. I was not able yet to look into that but supporting lazy loading is on the list of features. I have not tested it yet, but I think it should be easily doable, as you could use dynamic imports as the value for a catalog component already. Maybe you can test this on your own. Feel free to create a PR and suggest a solution.
