[ERROR] [localization.util.crop_box_filter_measurement_range]: The pointcloud layout is not compatible with PointXYZIRCAEDT or PointXYZIRC. Aborting

Expected datatype XYZIRC

name	datatype	derived	description
X	FLOAT32	false	X position
Y	FLOAT32	false	Y position
Z	FLOAT32	false	Z position
I (intensity)	UINT8	false	Measured reflectivity, intensity of the point
R (return type)	UINT8	false	Laser return type for dual return lidars
C (channel)	UINT16	false	Channel ID of the laser that measured the point

Actions needed

1. RING >> rename to CHANNEL
2. RETURN TYPE >> 0
