Subtask: Use the OpenCV function for distance_to_marker

[onkoe]

Currently, we have a weird (and custom) implementation of OpenCV's Euclidean distance formula. https://docs.opencv.org/4.x/db/da9/tutorial_aruco_board_detection.html

The goal of this issue is to shift away from the weird math we are currently using and instead use the much simpler, built-in function. Then, we can test the built-in function to see if there's any reason we are using the math instead.

This would use an OpenCV binding that is not currently available in Python.
