v2.0.3 for ROS 2 Iron Irwini

New features

• Add rmw_get_gid_for_client and stubs for other new rmw functions #99

Bugfixes & refactorings

• Fix macOS build #90
• Set C++ standard in accordance with iceoryx #93
• Use rcutils_get_executable_name to get the name of the process #94

Known limitations

• Service/Client communication
  • The request payload pointer is stored in the iceoryx server abstraction. It would be better to extend rmw_request_id_t and add a void * there if accepted in upstream rmw. For now, the limitation exists to always call rmw_take_request followed by rmw_send_response and not call e.g. 2x times rmw_take_request and then 2x rmw_send_response.
