LIO-SAM brakes tf tree

[ZhongmouLi]

I run lio_sam in ros2 humble simulation, and I find lio_sam always brakes tf tree of robot.

Lets say I have a simple robot with a tf tree being

After running lio_sam, I get a new tf tree

and robot in Rviz

This is because LIO-SAM always pubs tf transform between odom and lidar, even they are not connected.

[ZhongmouLi]

solved: in simulation, robot already has a tf tree that links lidar and base_link, so we should make lio-sam stop publishing transform between odom and lidar.
