[Feature REQ] Read layout info and use it to deisplay initial nodes order

[bogris]

It would be nice to have the initial layout in the inspector same as in the other views.

I am using the VScode extension heavily, and I saw that the layout is ported nicely to the Studio.
I know the positioning meta is a comment, but it is in the codebase :)

As the inspector is run in the codebase also, maybe you figure out a way to share this info trough to the inspector UI.

1. For starters, I am thinking at a simple implementation where we can supply the meta positioning string directly.
2. Another option I see is to point the inspector to the file that holds the meta and you can use the logic that is built into the Studio importer.

I am asking this because as we scale to over 10-20 states, one of the big advantages stately brings to the table is establishing a visual map of the flow.
Especially when developing, i see that the inspector brings a lot of value as I can just glance at it and I know what's what.
