    ASK demodulator.

    The input is complex baseband.  When packets are demodulated, they are passed to the
    app via the callback.

	Hierarchical block for Amplitude Shift Key (ASK) demodulation.

	The input is the complex modulated signal at baseband.
        Demodulated packets are sent to the handler.

	@param fg: flow graph
	@type fg: flow graph
        @param access_code: 16-bit sync code
        @type access_code: string of length 8
        @param callback:  function of two args: ok, payload
        @type callback: ok: bool; payload: string
        @param threshold: detect access_code with up to threshold bits wrong (-1 -> use default)
        @type threshold: int

        See ask_demod for remaining parameters.
