Component | Graph: ELK Support

[rokotyan]

This PR implements initial ELK support, which is the best layout engine for diagrams as of today. ELK Layered Layout can be a good alternative for our Parallel Layout when you need more nesting (panels within panels ...). Besides that ELK has other layouts available. #141

This is really cool! Nice work.

One thing I'm not sure about: is there a straight forward way to change the layout algorithm? Because when I change the dev example's props to layoutElkSettings={{ 'elk.algorithm': 'radial' }} I get an error, but inside the component itself I can just add that to the layout options and it works:

@reb-dev Thanks! ELK has a quite sophisticated layout configuration logic that I've tried to wrap it a little to suit our primary use case out of the box. But it looks like it broke some other things, so I've simplified my logic to avoid issues like the one you've found.

Looks good!
