Zed-ros-wrapper: Simplify repository

[rbonghi]

I'm using wstool to download quickly a catkin working space for my project and rosdep to install all required dependencies .

After building the _catkin_ws_ I usually start rosdep with this option (point 2.3.2)

rosdep install --from-paths src --ignore-src -r -y

This "magically" installs all the packages that the packages requires.
But when rosdep read all package.xml in this repo, the system start to download all dependencies not only for zed-wrapper but for all examples and tutorials contained in this repository, a significant space for an embedded device (like NVIDIA Jetson Nano).

Is it possibile to split this repository in one with only the zed-ros-wrapper and a secondo with examples and tutorials?
