clawbot 6dd22bcb73 exif() returns every EXIF tag in the file (closes #156)
check / check (push) Waiting to run
`photo.exif()` returns `ExifTags`: every EXIF tag exifreader reads from the file, keyed by tag name, each with exifreader's `id`, `value`, `description` and `computed`. The embedded thumbnail's tags are under `Thumbnail`, without the thumbnail image. A file with no EXIF, or a video, gives `{}`.

The thirteen typed methods stay. Each picks its field from the tags `exif()` returns through `readPhotoExif`, which now takes the tags instead of the bytes. GPS latitude and longitude are worked out from their tags and reference tags, since exifreader's computed position is not among the tags.

Also closes #148.

clawbot 67d554fb46 exif(): read HEIF/HEIC originals with exifreader (closes #145)
check / check (push) Successful in 2m10s
`photo.exif()` and `quak backup-metadata --exif` now read EXIF through `exifreader`. HEIC/HEIF originals get EXIF, including a live photo's image, as do the other formats `exifreader` reads. It replaces `exif-reader` and the hand-written JPEG scan. `PhotoExif` is unchanged.

The `backup-metadata` dump now holds `exifreader`'s tag output, with unnamed tags keyed `undefined-` plus their number. GPS altitude without a reference counts as above sea level. A latitude or longitude without its hemisphere tag, an unreadable text tag, and a date the parser rejects each give no field.

Licence: `exifreader` is MPL-2.0, used unmodified.

clawbot 2b598d3622 Photo: save path, is-local, content bytes, metadata and EXIF getters (closes #141)
check / check (push) Successful in 1m24s
`Photo` gains:

- `savePath` and `isLocal`: synchronous, disk only. Where `lib.backup()` writes the original under the library's `downloadDirectory`, and whether all of it is there; a copy only in the cache does not count.
- `content()` and `exif()`: async, may download. `exif()` reads the common EXIF fields of a JPEG and returns `{}` for anything else.
- The getters `modifiedAt` and `hash`, also on `PhotoRecord`, and `year`.

For a live photo the backup has not stored yet, `savePath` carries the title's extension, and the image may be stored under a different one. The JPEG EXIF scan moved to `src/exif.ts`. The exported `PhotoContent` interface gains `savePath` and `isLocal`.

Judgement call: `iso` is read only when the file stores it as a single number.
