Provide more detailed information about each package in the output of show projects

[dmaklygin]

The current command is quite powerful and offers many options. However, in some cases, just getting a list of package names might not be enough—we may also need the location of each package.

With that in mind, could you add a full graph output for the command when an additional option like --full-output is passed?

Here, we convert the graph to a set, but we cut here a valuable information.
