  Biphase-L (Manchester) Decoder for Cospas-Sarsat 406 MHz beacons.

  Biphase-L encoding represents:
  - Bit 0: Low-to-High transition at bit center
  - Bit 1: High-to-Low transition at bit center

  Input: Unpacked byte stream of Biphase-L encoded symbols (2 samples per bit)
  Output: Unpacked byte stream of decoded bits

  Decimation factor: 2 (two input samples produce one output bit)
