- The output for `--output-sort=id` matches `--output-sort=offset` for
the available readers. Tests were updated accordingly.
- For `--output-sort=none`, and per `LVReader::sortScopes()`,
`LVScope::sort()` is called on the root scope.
`LVScope::sort()` has no effect if `getSortFunction() == nullptr`, and
thus the elements are currently traversed in the order in which they
were initially added. This should change, however, after
`LVScope::Children` is removed.
