Inverse Fast Fourier Transform for 1-dimensional, complex frequency domain data. Returns real time-domain data, rescaled by data length, so that IFft(Fft(x)) = x. Input is expected to be in interleaved format (Real_00, Imag_00, Real_01, Imag_01), satisfying the symmetry condition. For even-length input, input[1] should equal Real[length/2], for odd-length input, input[1] should equal Imag[(length-1)/2].
