Resolved against rb-base-36: Scanned keeps the base's rewrite flag next to magic and tag; Exif keeps the Panasonic lens fallback; locale catalogs merged (one duplicate key dropped).

photo.allMetadata listed no lens for a RW2: Panasonic writes no Exif
LensModel, and the maker note that names the lens is in the Exif of
the embedded JpgFromRaw. List that maker note tag (LensType, 0x0051)
as a row of a Panasonic group, the same name photo.inspect shows, for
a RW2/RWL and for a JPEG with the note in its own Exif.
Checked on the CC0 sample DMC-G80 P1000403.RW2: Panasonic / Lens Type
= SIGMA 60mm F2.8 DN.
Panasonic writes no Exif LensModel. The lens name is in its maker note
(LensType, 0x0051), and a RW2 or RWL keeps that maker note only in the
Exif of its embedded JpgFromRaw (IFD0 0x002E), not in the raw's own Exif
IFD. When LensModel is absent, read it from the maker note, and for a
raw from the JpgFromRaw's Exif.
Checked on the CC0 samples DC-GX9 gx9_1_1.RW2 (LUMIX G 25/F1.7) and
DC-S5 P1047510.RW2 (LUMIX S 85/F1.8), also through the sparse header
plan an import uses.
Read the autofocus point from Sony maker notes (FocusLocation 0x2027, FocusFrameSize
0x2037, FocusMode 0x201b, AFAreaModeSetting 0x201c, AFTracking 0x2021 and the area mode
used from the enciphered 0x9402 block), for the ILCE-1 and ILCE-7SM3, whose layout was
checked against ExifTool's output on 333 real ARWs. Manual focus, centre-only Multi
reports and unchecked bodies give no point. The box is stored on the upright photo as
Meta.focus (omitted when unknown; no catalog format change), filled at import and by
Reload from Disk.
View > Show Focus Point (Alt+F) draws it in Detail, Compare and Survey through rotation
and crop; View > Zoom to Focus Point (on by default) makes Toggle Zoom centre on it; the
Info panel shows "AF-C · Wide · Animal Eye Tracking". photo.inspect returns meta.focus.
