@brief Initialization function for the Q31 IIR lattice filter. @param[in] S points to an instance of the Q31 IIR lattice structure. @param[in] numStages number of stages in the filter. @param[in] pkCoeffs points to the reflection coefficient buffer. The array is of length numStages. @param[in] pvCoeffs points to the ladder coefficient buffer. The array is of length numStages+1. @param[in] pState points to the state buffer. The array is of length numStages+blockSize. @param[in] blockSize number of samples to process.
