matlabbe 3f6adad463 ROS2 various QOL updates (preparing new binary release) (#1225)
* Updating examples and README

* updated main readme

* odom: Added always_check_imu_tf parameter. sync: increased default sync_queue_size from 2 to 5 (to be more flexible to different hardware), added input and output diagnostics. rtabmap_viz: fixed node with same name redeclared warning.

* update readme

* Added husky demo

* converted demo_robot_mapping.launch to ros2

* Converted stereo_outdoor demo from ros1 to ros2

* Converted multi-session demo to ros2

* Converted demo_find_object launch to ros2

* renamed files

* uniformized default qos, increased sync_queue_size default to 10

* Added vlp16 + imu example

* Added husky 3D lidar demos

* moved demos in subdir

* Added vlp16+zed example

* rtabmap_viz: ignore odom update if tf not ready when not using topic (to avoid showing red screen). Added champ VSLAM demo.

* forwarded camera_model arg for zed examples, removed qos for turtlebot4 demo

* pointcloud_to_depthimage: added more error logs, removed output camera_info published twice and match ros1 namespaces

* Created two base general examples for 3D lidar usage, then create hardware specific examples on top of them.

* Added isaac sim demo

* Final update of all demos. Fixed MapCloud rviz plugin crashing when floor/ceiling filtering is used and resulting cloud is empty.

* Fixed 2d scan deskewing output frame, moved nav2 params under "params" folder, added number of topics processed/dropped for odometry, added icp_odometry option for turtlebot3 scan-only demo.

* rtabmap_demos: added README with examples

* Added TOC

* bump version to 0.21.9

#
# Note: Make sure you have this fix for turtlebot4_description https://github.com/turtlebot/turtlebot4/pull/434,
# otherwise, the lidar and camera point cloud won't be aligned correctly.
#
# Example:
# 1) Launch simulator (turtlebot4, nav2 and rtabmap):
# $ ros2 launch rtabmap_demos turtlebot4_sim_demo.launch.py
#
# 2) Click on "Play" button on bottom-left of gazebo.
#
# 3) Click on double points ".." button on top-right next to power button to undock.
#
# 4) Move the robot:
# b) By sending goals with RVIZ's "Nav2 Goal" button in action bar.
# a) By teleoperating:
# $ ros2 run teleop_twist_keyboard teleop_twist_keyboard
# c) By using autonomous exploration node (tested with https://github.com/robo-friends/m-explore-ros2):
# $ ros2 launch explore_lite explore.launch.py
