- Add conversion node to use RS16 data (this may also work with other RS Lidars, but some things would need to be checked)
- Improve approximate point-wise timestamps computation : the computed
timefield is now the time offset to add to
header.stampto get "real" point-wise time. This includes adding the
timestamp_first_packetfor Velodyne conversion node.
rpmto mimic ROS drivers parameters.
