Given a <spec> argument, print out the fully qualified package ID specifier.
This command will generate an error if <spec> is ambiguous as to which package
it refers to in the dependency graph. If no <spec> is given, then the pkgid for
the local package is printed.

This command requires that a lockfile is available and dependencies have been
fetched.

Example Package IDs

           pkgid                  |  name  |  version  |          url
    |-----------------------------|--------|-----------|---------------------|
     foo                          | foo    | *         | *
     foo:1.2.3                    | foo    | 1.2.3     | *
     crates.io/foo                | foo    | *         | *://crates.io/foo
     crates.io/foo#1.2.3          | foo    | 1.2.3     | *://crates.io/foo
     crates.io/bar#foo:1.2.3      | foo    | 1.2.3     | *://crates.io/bar
