docs: getLinks(string) -> list((string, bool, bool, bool))
          A list containing id of successor lane together with priority, open and foe
          for each link.
          if extended=True, each result tuple contains
          (string approachedLane, bool hasPrio, bool isOpen, bool hasFoe,
          string approachedInternal, string state, string direction, float length)
