Module day_20

This is my solution for Advent of Code - Day 20: Race Condition

parse_input turns the input file into a RaceTrack

RaceTrack::cheatssolves both parts. It uses RaceTrack::get_track_positions to turn the grid data into an indexed list of the spaces visited, then calculates those that match the part’s criteria and counts them. There are some coordinate utilities in CoordinateExtensions.
