Port to humble

This has all the changes I made to port to humble. This duplicates other work, however there are unique pieces that can be covered.

@Ryanf55 Could you switch the base branch of the PR to https://github.com/ethz-asl/grid_map_geo/tree/ros2 ? Then would be easier for the relevant diff

Done! I'll have to fix merge conflicts now, but it should give you the basic idea.

I've fixed merge conflicts. Ready for review.

Awesome! Thanks! Looks good for me!

Realized that the build test of ROS Noetic should not be valid for this branch anymore. Will address in a follow up PR

@Ryanf55 Should we make the ros2 branch the default? or would you prefer a separate repository? I can also create a grid_map_geo2 under the ASL org if you prefer this way

I've generally seen just updating ros2 to be the default. Since the code is largely the same, people still use ROS1, having it all in one repo makes backports easier. I don't have a strong preference.
