Out of range become nan instead of inf. #61
Description
I read in the wiki https://wiki.ros.org/depthimage_to_laserscan and it says ranges less than range_min will be output as -Inf and +Inf for range_max.
When I try with range_min=0.3 and range_max=4.0, all values not in range become nan. Here is message from rostopic echo https://drive.google.com/file/d/1YSh61ATBp4Xuy6y_YcDfNicW1LBbvW1E/view?usp=sharing
But this is the result after I increase range_max to range_max=10.0

My sensor is realsense d455 and depth image encoding is 16UC1.
ROS distro in noetic. This is how i call node in launch file.
