      public static CqlDurationLiteral parse(String stringDuration)
      Parses a CQL duration literal into a CqlDurationLiteral. A leading - is stripped and applied as a sign to all three components. The remainder is dispatched to the matching pattern-specific parser by parseUnsigned(java.lang.String).
      Parameters:
      stringDuration - the duration literal to parse; must not be null, empty, or blank
      Returns:
      the parsed duration, decomposed into months, days and nanoseconds
      Throws:
      IllegalArgumentException - if stringDuration is null, empty, or blank
