Set row_step after resizing point cloud

[HansRobo]

Problem

I found row_step error in Foxglove Studio for point cloud topic from OrbbecSDK_ROS2@c0c14f5 with ORBBEC Femto Boto, like the image below.

Solution

Since raw_step was not updated after invalid points were removed, I added a line to update it.

And I had no error with the fixed version of OrbbecSDK_ROS2.

Note

sensor_msgs::PointCloud2Modifier::resize is a function often used to update row_step, but if consistency other than row_step has been achieved first, the row_step update will be skipped. https://github.com/ros2/common_interfaces/blob/jazzy/sensor_msgs/include/sensor_msgs/impl/point_cloud2_iterator.hpp#L127-L130
