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.
