ROS package for running MOTLEE frame alignment
Example node architecture:
Put mapper and frame_aligner within robot's namespace and give the frame_aligner node a list of neighboring robots. See two robot example launch file.
mapper node listens for detections (in its body frame) and poses and outputs a map in the world frame.
frame_aligner node listens to all the different maps and publishes frame_align messages containing relative transformations between robot frames at a selected frequency.
