Contour detection example over a punch card image

This Xcode playground is based on the example showed by Frank Doepke, Apple engineer, on the WWDC'2020 talk named "Explore Computer Vision APIs".

It shows how to perform contour detection over a punch card image, applying a couple of CIFilters to reduce the number of contours of interest.
