BEVFusion ROS2 wrapper working

[nlitz88]

Some different options:

• https://github.com/NVIDIA-AI-IOT/Lidar_AI_Solution/tree/master. This would be good at the core, but this doesn't contain any ROS2 code.
• https://github.com/linClubs/BEVFusion-ROS-TensorRT I'm not 100% sure, but this is the original wrapper I was talking about. I'm pretty sure they utilize the "Lidar_AI_Solution" system above and just create a ROS2 wrapper around it. Not totally sure, but this seems to be what they are doing.
