Add humble CI

[Cakem1x]

This PR adds a Github Action for CI, based upon actions from ros-tooling.

It will check that

• we have all dependencies specified
  • deps are installed via rosdep apt
  • for deps not available this way, we can add them to the source_dependencies.yaml file. Caveat: This will increase build times, since all packages in this repo will get build and tested.
• build of workspace succeeds
  • workspace consisting of mesh_tools and repos from source_dependencies.yaml
• test of workspace succeeds

Check out this action log, for example, if you want to see more details.

Current job runtime is 10min. I think we can improve this, e.g. via caching or by tweaking the parameters, but I suggest doing that at a later in a separate PR if the need arises.

Wow, that's long. But ok for now.

Yes, I think we should look into

• GitHub Action caching
• Building only mesh_tools pkgs and its source deps
  • on CLI, you could do `colcon build --packages-up-to $(colcon list --base-paths $PATH_TO_MESH_TOOLS_REPO). Maybe there is an option that does a similar thing in the ci action
• Testing only mesh_tools pkgs (and not its source deps)
  • e.g. via `colcon test --packages-select $(colcon list --base-paths $PATH_TO_MESH_TOOLS_REPO). Maybe there is an option that does a similar thing in the ci action
