Thank you for the PR! Unfortunately I don't think we should merge this one. ROS Noetic will reach end-of-life on May 31st, 2025. Every change comes with a risk of introducing regressions, and there isn't much time left to fix them. I'm closing pull requests that add features so that the remaining time is allocated towards bug fixes and compatibility with newer Ubuntu distros. |

This PR adds support for YUV420 (or I420) images.
I420 is the most common YUV format and is adopted by most Image Sensor Processor (ISP) chips, specifically this was implemented to work with gstreamer based v4l plugins
I420 consists in 12 bits per pixel, which is implemented in OpenCV as a cv::Mat with one 8 bit channel with 1.5x the number of rows of the actual image.
