[fix][WIP] Fix Hesai pcap readers

• For PandarXT

  • Points coming from the Lidar were weirdly doubled. These changes allow to remove duplicated points
  • A criterion on distance is removed because it rejected correct points.

• For Pandar128

  • A warning of "too many points was appearing when opening a Pandar128 pcap file. A criterion on invalid distance is added to not take points that have a 0 distance / 0 intensity and this solves the previous issue.
