Все конфигурационные файлы переехали в пакет `iiwa_config`. также там появился общий конфигурационный файл, который упращает запуск `digital_twin.launch.py` Добавлен дополнительный пакет `iiwa_utils`, в который переехал весь код с папки `iiwa_bringup/utils`, а также все тестовые ноды переехали с `iiwa_object_spawner` в этот пакет Пакеты `iiwa_bringup` и `iiwa_description` переведены на `ament_cmake` для дальнейшего удобсва - пакеты не будут содержать код для реализации
