[feat][ROS] Create pose SLAM frequency feature
Add the frequency feature of LidarView to ROS wrapping.
Reminder of SLAM frequency feature:
-
At each SLAM output, the trajectory is updated, adding the last poses computed from the previous frame input at a specific frequency. If no external sensor are used, the poses are interpolated. If a pose sensor or an IMU is used, the interpolation is performed between this external sensor measurement.
-
If the frequency is set to -1, one pose per SLAM output is computed.
