Detect dock

[JanelleCai]

• use the point cloud / camera to determine the location of the dock.
  • currently the yolov8 model can detect a dock from an image (i'm not sure if the dock from the docking task or the real dock that people stand on are different classes. perhaps feed it an image to check. you can find images from roboboat by searching roboboat on roboflow and scrolling through some projects / datasets)
• this should output the position of the dock and useful information about the dock.
  • need to determine what this means. ie. just the centroid of the dock is not useful information, and we want to know things like its depth.
  • communicate with @knosmos and @sanjithudupa about what information about the dock is desired / useful, since they worked on the docking logic.
