* Allow declaring uninitialized parameters Parameters can now be declared without a default value and without an override. Attempting to access a statically typed parameter that does not have value will raise an exception. Getting dynamically typed parameters will return an unset parameter value. This change is equivalent to that made in rclcpp: ros2/rclcpp#1673 Signed-off-by: Jacob Perron <jacob@openrobotics.org> * Fix flake8 Signed-off-by: Jacob Perron <jacob@openrobotics.org> * Minor refactor Signed-off-by: Jacob Perron <jacob@openrobotics.org> * Don't allow static parameters to be undeclared Signed-off-by: Jacob Perron <jacob@openrobotics.org> * Return alternative for uninitialized parameters in get_parameter_or Signed-off-by: Jacob Perron <jacob@openrobotics.org> * Ditto for dynamic parameters This is the same behavior as rclcpp. Signed-off-by: Jacob Perron <jacob@openrobotics.org> * Fix lint Signed-off-by: Jacob Perron <jacob@openrobotics.org>
