Adds support for Bayer image encodings in
ColorSubscriber::fillInput()by treating Bayer images as color inputs and converting them viacv_bridge::toCvCopy(..., RGB8).This allows Hydra-ROS to work with camera drivers that publish raw Bayer data (e.g.,
bayer_rggb8) without requiring manual debayering logic. Existing color and mono image handling is unchanged.
