 SYS=pink_noise_subsystem(NAME, SR, NUMCHANNELS, BLOCKSIZE)
 Creates a module which outputs pink noise at a specified standard
 deviation.  Internally, the module uses a white noise generator
 followed by an IIR filter.  Arguments:
    NAME - name of the module.
    SR - sample rate.  This must be set since this is an output module.
    NUMCHANNELS - number of interleaved channels in each output pin.
    BLOCKSIZE - number of samples per output channel.
