Request: Preview of embedded needuml / needarch

[PhilipPartsch]

It would be cool if we would have a fast preview of the needuml / needarch during authoring.

Solution Idea:
Could we have the meta model form needs.json in the memory to pre-render the output?

Update: Moved this issue from the Sphinx-Needs repo.

I think your change is for the VS Code support via esbonio.
This was removed from Sphinx-Needs and is now a dedicated repo: https://github.com/useblocks/sphinx-needs-vscode

But I guess it should be doable, based on a given needs.json.
