Date a photograph from its name when its header has none

WhatsApp strips every EXIF tag and names the file "WhatsApp Image
2023-06-15 at 07.00.42.jpeg"; Windows Phone, Android cameras and
darktable's import put the date in the name too. Those images sorted
after everything else and were absent from the timeline.

name_dates reads a date (and a time, when one follows) from the file
name, then from the innermost folder that states one. A sequence number
after a date is not read as a time, and a bare year folder is not a date.
EXIF always wins: only examined rows still undated are filled.

The sweep and the metadata repair fill as they mark an image examined,
and the open backfill fills catalogs examined by earlier builds. On the
reference library that takes 274 undated images to 10; the no-op case is
a seek on images_captured, 0.6 ms an open.
