Add useful macros for SLAM use/debug
These are useful macros to easily load data, init a SLAM filter on it, then track the last pose of the output trajectory:
- load_lidar_data is an example/template macro to easily load a specific LiDAR recording
- init_slam can be used to instantiate a SLAM filter on a LiDAR source and set nice display settings
- focus_last_pose set at each timestep the focal point and center of rotation on the last pose of a trajectory
- attach_last_pose does the same thing as focus_last_pose, but also set a fixed relative orientation (as if the camera was attached to this last pose)
- slam_kp_matching outputs the current keypoints and color them by their matching status, which may help debugging why registration fails.
