@brief Initialization function for the Q31 FIR decimator. @param[in,out] S points to an instance of the Q31 FIR decimator structure. @param[in] numTaps number of coefficients in the filter. @param[in] M decimation factor. @param[in] pCoeffs points to the filter coefficients. @param[in] pState points to the state buffer. @param[in] blockSize number of input samples to process per call. @return The function returns ARM_MATH_SUCCESS if initialization is successful or ARM_MATH_LENGTH_ERROR if blockSize is not a multiple of M.
