Draws boundary lines of the path defined by the cones, and saves the result as answer.png

The image processing pipeline I used was:

1. Extract red channel from image
2. Apply threshold to isolate really-red objects
3. Find contours in image
4. Generate a bounding box around each contour
   • Throw out contours with too small an area
   • Throw out contours that are too squat (can't be cones)
5. Find center of contour
6. Draw regression lines using contour centers as points on the lines

I struggled to find a good way to bound the different cones since I have limited experience with OpenCV. I'm happy with the solution I ended up with.
