Your LIDAR uses the Delta-2A / 3irobotics protocol (same as LDS08RR in the kaiaai/LDS repo), NOT the Neato XV11 protocol.

  Key issues with the old code:
  - Start byte is 0xAA, not 0xFA. The 0xFA bytes you were seeing are just random data/distance values
  - Packet size is variable (typically 72 bytes: header says packet_length=70 + 2 for the start/length fields), not a fixed 42 bytes
