Allow generating tree/graph for a union of subgraphs of the project

That would probably not work for generate tree since it would generate disconnected sub-graphs which by definition are not a tree any more. Unless one was to search for the corresponding root nodes of each disconnected sub-graph/-tree and print out multiple trees. But then again that isn't too bad actually and being able to focus on more than one path seems useful, indeed. 🤔

It would require a couple of internal logic changes, as well as a change from --focus-on accepting a single Path (e.g. foo:bar) to a UseTree (e.g. foo::bar::{self, baz}).

@giannissc you might want to give v0.7.0 a test run, which added support for accepting a full use-tree (e.g. foo:bar::{self, baz, blee::*}) for --focus-on, instead of just simple paths. 😉

Will give it a shot! Thanks 🙂
