Created the 'aspect-deps' command described in
<https://github.com/BladeRunnerJS/brjs/wiki/Peering-in-to-the-bundling-black-box>
to help Jan understand the cause of some of the error messages he is
seeing, as the old command is no longer relevant -- the plan is to
create all 4 commands described by that wiki
page.
Added a 'workbench-deps' command to complement the 'aspect-deps' command
that was created previously.
