        public static MetaShift.GaloisData forPeriodAndBankModulo​(long period,
                                                          int bankModulo)
        Look up the valid Galois LFSR feedback register values for the required resamplePeriod.
        Parameters:
        period - The minimum cycle resamplePeriod required
        bankModulo - A deterministic selector which will always select the same pseudo random bank
        Returns:
        A valid Galois LFSR feedback register
