Starting Camera Node Example

This example demonstrates how to launch camera node in ROS2 with launch file and how to override some parameters of the launch file through the command line:

ros2 launch realsense2_camera pointcloud.enable:=true align_depth.enable:=true

This will stream all sensors that are enabled in the launch file (Depth, Color, Gyro, Accel) and publish on the appropriate ROS2 topics

By overriding the pointcloud and align_depth enable parameters, we are enabling these post processing filters although both of them were turned off in the launch file.
