photo.exif() and backup-metadata --exif read EXIF with exifreader,
which reads JPEG, HEIC/HEIF, AVIF, PNG and WebP, so a HEIC original or
a live photo's HEIC image gets its EXIF. exifreader replaces
exif-reader and the hand-written JPEG segment scan. PhotoExif is
unchanged. The exif field of backup-metadata --exif is now
exifreader's tag output, and exifRaw holds the whole EXIF block it
could not read. Tests use a real 933-byte HEIC fixture, test/exif.heic,
whose recipe is in test/exif-heic.ts.

# Completed Steps
- 2026-10-01: `photo.exif()` and `backup-metadata --exif` read EXIF from
HEIC/HEIF originals, a live photo's HEIC image included, as well as JPEG and
the other image formats `exifreader` reads (issue 145). `exifreader` replaces
`exif-reader` and the JPEG segment scan; `PhotoExif` is unchanged. The `exif`
field of `backup-metadata --exif` is now exifreader's tag output, and
`exifRaw` holds the whole EXIF block it could not read. The tests use a real
HEIC, `test/exif.heic`.
- 2026-10-01: A `Photo` has `savePath`, `isLocal`, `content()`, `exif()`,
`modifiedAt`, `hash` and `year` (issue 141). `savePath` is where
`lib.backup()` writes the original under the library's download directory; for
