qos overriding support for republish.cpp on humble

republish.cpp on humble doesn't support qos overriding on input and output topics when used in cli.

ros2 run image_transport republish compressed raw \
 --ros-args -r in/compressed:=/camera1/image_compressed \
 -r out:=/camera1/uncompressed

The rolling branch has a completely different implementation of republish.cpp - i was curious if it would be possible to backport?

if a backport would break image_common - would it be okay to make a configurable rmw_qos_profile_t struct for configuration when vargv.size() < 3 and set image_transport::create_subscription() and image_transport::create_publisher(). Would this be reasonable?

Start in image_transport/src/republish.cpp at the referenced lines and compare the rolling branch's republish.cpp implementation. Verify how the Humble CLI creates the input subscription and output publisher, then confirm that QoS overrides work for both topics without breaking image_common compatibility.
