clj allows us to specify local deps with the
:local/root coordinate type, but when multiple developers share a
deps.edn for a project, it is often the case that they have placed dependencies in different locations on their filesystems.
:local/root allows relative paths, which helps with this a bit, but this doesn't allow the flexibility of lein checkouts, which are local file system symlinks that are not stored in version control. Does the clojure cli allow something like that?
