Spatial Association Node (bbox_2d_3d revamp) #217
Description
Main Objective: rework the existing node with a tighter scope; make more nodes that handles lidar-preprocessing. The node should only handle association logic.
- dynamic topic subscription (specify the number of cameras in config; n_cameras->n_topics)
- look into ros plugins; projection_utils is currently just a bunch of helper functions for projection, transformation and association
- ros nodes should be split into core and node, similar to the onboarding
