  Apollo PM Demodulator

  Extracts phase modulation from complex baseband signal.
  The spacecraft PM deviation is 0.133 rad (7.6 degrees) peak.
  Uses a carrier tracking PLL followed by phase extraction.

  Parameters:
    carrier_pll_bw: PLL loop bandwidth in rad/sample (default 0.02)
    sample_rate: Input sample rate in Hz (default 5.12 MHz)
