Wider install

[pulver22]

This pull request introduces new launch files for simulation and navigation, adds two new Gazebo models (fire_extinguisher and first_aid_kit), and updates the package setup to include these assets and new directories. The changes enhance the simulation capabilities and organization of the cmp9767_tutorial package, making it easier to launch single or multi-robot simulations and to use custom models in Gazebo.

Launch System Enhancements:

• Added limo_simulation.launch.py and limo_simulation_multi.launch.py to support launching single and multi-robot simulations in Gazebo, including robot state publishers, joint state publishers, entity spawning, and RViz integration. These files also set up environment variables for model paths and provide flexible launch arguments for simulation configuration. [1] [2]
• Added limo_navigation_bringup.launch.py to streamline launching navigation-related nodes and lifecycle management for the robot, with configurable parameters and modular inclusion of controllers.

Gazebo Model Additions:

• Added fire_extinguisher model with configuration and SDF files (model.config, model.sdf), representing a simple red cylinder for use in Gazebo simulations. [1] [2]
• Added first_aid_kit model with configuration and SDF files (model.config, model.sdf), representing a green box for Gazebo simulations. [1] [2]

Package Setup Improvements:

• Updated setup.py to use os.path for path handling, and expanded the data files section to install launch files, configuration files, parameters, URDFs, worlds, models, and meshes into appropriate package directories, enabling proper ROS2 resource indexing and distribution. [1] [2]

These changes collectively improve simulation support, asset management, and launch flexibility for the tutorial package.
