ConsumerThread terminates immediately

[Tacha-S]

When running cameracheck from the camera_calibration package in ROS2 Jazzy, it subscribes to an image topic only once, performs the check, and then terminates. This behavior might be fine if the calibration board is always visible at the time of launch. However, it is quite inconvenient when the board needs to be moved into view after starting the node.

Lines 77 to 82 in bb4ab63

	def run(self):
	while rclpy.ok():
	m = self.queue.get()
	if self.queue.empty():
	break
	self.function(m)

Additionally, the results are output via print(), which may not be visible when launched through a launch file or similar methods. It would be better to use the ROS logger for consistent and accessible logging.
