Measure what the cheapest SCRFD actually costs in faces

Browse Source 
§1 chose scrfd_500m on FLOPs and never measured the recall it gave up.
A dr-ui example now runs several detectors over the same sample of
stored proxies, matches boxes by IoU against the first, buckets the
result by face size, times each, and writes contact sheets of the
disagreements in both directions — because a count of extra faces says
nothing until someone has looked at whether they are faces.

Over 400 proxies from the reference library: 2.5G finds 14% more faces
for 12% more time, 10G a further 12% for 3.1× the time. The extras are
small real faces. The 86 faces only 500M found are a dog a dozen times,
a stop sign, a wheel and the backs of heads. Recorded in faces.md §12.3.
