Hide GDAL from public interface, fix export

* Enforce export in CI
* Hide implementation details of GDAL in implementation
* Switch to build-scope includes
* Install headers per latest ament recommendations to allow package: https://docs.ros.org/en/humble/How-To-Guides/Ament-CMake-Documentation.html#adding-targets
* This is crucial before realeasing as a library
* Remove unused yaml dependency
* Add all missing libraries in ament_export_dependencies
* Fix a few typos in comments
* Add badges for all jobs but point them to the default ros2 branch
  rather than any branch
