 M=wav_interp_oneshot_source_module(NAME, NUMCHANNELS, BLOCKSIZE, SAMPLERATE)
 Creates a source module that connects to a streaming buffer module and outputs blocks
 of data.  The function includes linear interpolation allowing playback to be slowed down and
 speeded up.  This version uses float wave data and a float fIndex register for efficient
 implementation.  This version is a "one shot player" in which the playback is triggered 
 by an input pin and then stops after the WAV data has been played once.  Arguments:
    NAME - name of the module.
    NUMCHANNELS - number of interleaved channels in each output pin.
                  By default, NUMCHANNELS = 1;
    BLOCKSIZE - number of samples per output channel.  By default,
                BLOCKSIZE = 32.
    SAMPLERATE - sample rate of the output signal, in Hz.  By default,
                 SAMPLERATE = 48000.
