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.
