 * Finds needed file through Document API for SAF. It's not optimized yet - you can still gain wrong URI on
 * files such as "/a/b/c.mp3" and "/b/a/c.mp3", but I consider it complete enough to be usable.
 *
 * @param dir      - document file representing current dir of search
 * @param segments - path segments that are left to find
 * @return URI for found file. Null if nothing found.
