Possible copy pasta in ROS2Visualizer.cpp

[Galto2000]

Howdy folks!

I am wondering if in the following line below, the recalled parameter should be written in the variable cam_topic1 instead of cam_topic0 ?

open_vins/ov_msckf/src/ros/ROS2Visualizer.cpp

Line 182 in db026f3

_node->get_parameter("topic_camera" + std::to_string(1), cam_topic0);
