  Summary

  Adds library support for the LEGO Duplo Hub No. 16 (model label
  "HUB NO. 16 IC3072A-103651", BLE manufacturer data type byte 0x21).

  This hub uses the same LPF2 BLE service UUID as existing hubs but has
  a different port layout, device types, and command format to the
  original Duplo Train Hub (0x20).

  All commands and port assignments were confirmed by capturing Android
  Bluetooth HCI snoop logs of the official app and
  verified on hardware (ESP32-C6).

  Notes

  • Motor speed is variable pn the newer models as well
  • Tile/scene detection is handled entirely by onboard firmware reading
    tile colour and length — no BLE notification is sent when a tile is
    crossed
  • Device type 91 (port 0x33) has not been identified; it is registered
    in the port map but no commands targeting it were observed in app
    traffic
