  clar: support hierarchical test resource data Support hierarchical test resource data, such that you can have `tests/resources/foo/bar` and move the `bar` directory in as a fixture. Calling `cl_fixture_sandbox` on a path that is not directly beneath the test resources directory succeeds, placing that directory into the test fixture. (For example, `cl_fixture_sandbox("foo/bar")` will sandbox the `foo/bar` directory as `bar`). Add support for cleaning up directories created this way, by only cleaning up the basename (in this example, `bar`) from the fixture directory.
