README gives the false impression that conversion from Pointcloud2 to grid_map layers are available.

Hello,

The Readme gives the false impression that there are seamless methods of conversion available for using pointcloud messages. This issue #158 suggests that is not the case, there are some workarounds with converting to octomap then grid_map or heavy lifting needs to be done by porting elevation mapping code from ROS1 to ROS2. Please update the README.

Thanks.

Can you supply an example point cloud you'd like to convert?

There exists functions to convert from PCL types here: https://github.com/ANYbotics/grid_map/blob/master/grid_map_pcl/include/grid_map_pcl/GridMapPclConverter.hpp#L51

I think the question is clear enough as it is stated in the issue. The pointcloud is from the official sensor_msgs called PointCloud2. The grid map should be usable in real-time with data from a PointCloud2 topic.
