Make heading nodes follow heirachy

[ghost]

If i create a heading node in a file,say "org-roam" in linux.emacs.org, currently i t would show as linux:org-roam in the org-roam search
It would make more sense to generate the node hierarchy from the headings hierarchical location within the the file.
eg:
linux.emacs.org-roam

you could further extend this so that a subheading will automatically be inside the heirachy of its parent
eg: Heading "dendroam" under org-roam will be
linux.emacs.org-roam:dendroam

PS: awesome extension. Super helpful already :)
