Store.Import copies every member of every file group and the images
and videos under PRIVATE/M4ROOT to dest/YYYY-MM-DD/<file name>. The day
comes from the new Object.ModTime. A file group stays in the folder of
its primary member.
Each copy is read back and compared by SHA256. A file with the same
hash already there is skipped, and anything else there is a conflict
and left alone. One failed file does not stop the others. A cancelled
context stops at once and removes the partial copy.
Object.Hash now shares its reading code with the import.
Model: opus-5-5
GetStores replaces GetDCFStores: it takes a context, has no count
argument and returns a plain slice. GetStore returns the one mounted
card, or ErrNoStore or ErrMultipleStores.
Each Object keeps the fs.FS its card was read through, and Hash reads
through it, so tests can use fstest.MapFS. A cancelled context stops
the read before the next directory. Library errors wrap with %w.

Files in one DCF directory that share a file number are one file group,
as section 4.3.2.2 of the specification says. `Directory.FileGroups`
lists them, each with its numbers, its members and its primary member. A
lone file is a group of one. A group reports its member count and total
size.
Section 6.2.1.3 gives a DCF basic file priority over a DCF extended image
file. It says nothing about a DCF optional file, so ranking every `JPG`
first is a choice. A `THM` comes last.
`isImageFile` now accepts `.tif`, so a `TIF` counts as an image.
`Store.Images`, `Store.Videos` and the totals still count each file on
its own.

A card is now read by the naming rules in CIPA DC-009-2010, not by
looking for media extensions anywhere on the volume.
Store.Directories holds the DCF directories and their objects, with
directory and file numbers. Store.NonConforming lists everything else
under DCIM, including symlinks and names fs.FS refuses. Media under
PRIVATE/M4ROOT stays, with no DCF numbers. Media anywhere else is no
longer part of the store. A symlink is never followed, and a read error
names the card's mount point.

A card was detected only with M4ROOT at its root, and asking for two or
more stores returned one too few. A mount point now counts when its root
holds a DCIM or PRIVATE/M4ROOT directory, and the count is exact.
The check and the counting are split from the partition listing so tests
can hand them temporary directories.

Adopt the standard tooling from sneak/prompts: the Makefile and script/
entrypoints, lint and test stages in one Dockerfile, the lint config, the
CI workflow and the formatter settings. make fmt also formats Go, with a
pinned Go from script/bootstrap. The module path becomes
sneak.berlin/go/dcf.
Fix the lint findings in pkg/dcf. DCFStore becomes Store and DCFObject
becomes Object. Three behaviours change. An error listing mount points is
now returned, where a typo used to drop it. Store.String() prints Store{
instead of DCFStore{, and a negative total as 0 B instead of a huge size.
Replace the placeholder test with real tests. Move the README into the
required sections. make build compiles the library; it pointed at a
command that does not exist.
