I tested that the default pipeline works as before (autoware replay tutorial)

Also I tested the new files with:

ros2 launch common_sensor_launch robosense_Helios.launch.xml vehicle_mirror_param_file:=install/sample_vehicle_description/share/sample_vehicle_description/config/mirror.param.yaml  front_overhang
ros2 launch common_sensor_launch robosense_Bpearl.launch.xml vehicle_mirror_param_file:=install/sample_vehicle_description/share/sample_vehicle_description/config/mirror.param.yaml

*Note: I hardcoded vehicle dimensions to test this
