distances between 2 keypoints (within each individual, e.g. dist_snout_rightear for each individual)
distances between 2 individuals (across all pairs of the same keypoints, e.g. dist_individual1_individual2 contains snout-to-snout, rightear-to-rightear, tail-to-tail, etc. distances between individual1 and individual2)
distances between different keypoints of different individuals (dist_individual1snout_individual2rear contains the distances between individual1's snout and individual2's rear)
