In `line_follower fix two bugs and fine-tune parameters:
- Fix bug when calling `process_frame()` with
`text_bat = drone.get_battery()`. This triggers an error in
`cv2.putText()`. Replace by `text_bat = f"{drone.get_battery()}%"`.
- Move `h,w,c, = frame.shape` out of `if` statements to fix bug when
no contours found
