This allows an easy to use cli which invokes the export function to get
the keyring and uses the ownertrust and revoke functions to write all
artifacts into a target directory.

This gives more control over the export command that may be useful to
export a single packager to import it into gpg. This will also give more
flexibility to chain this function to the future verify stage.

By default the command exports the whole keyring directory.

Lets pass in a list of path's and reduce them to one set of path
iterables. This allows us to specify multiple source files/directories

Both commands are basically doing the same with the same params except
the target directory differs. Lets condense this behavior by using a
single subcommand with a boolean options.

Instead of always returning an artificial name try to preserve the
keyring filename if the split only yields a single certificate.

This helps to structure the layout of the repository better by having
one root folder that contains the actual decomposed keyring structure.

So far we have used singular for all directories, lets keep that for the
packager directory as well.

Allow short key id fingerprints to be used with the username derive
function by adding a glob in front of the fingerprint component.

Move the name cascade to derive the username into the
`convert_certificate` function which allows to use the
certificate_fingerprint directly instead of trying to find it by
splitting the certificate one more time before converting.

The certificate fingerprint in the convert function remains always the
same as we only process a single certificate and loop outside over
multiple keyrings. Therefor remove that layer from the data structures
and implicitly simplify all the assignments and usages.

This drastically improves readability and type safety when joggling with
different keys in the data structures.

pyproject.toml:
Configure isort to use single lines (one line for each import) to ease
merge conflicts.

keyringctl:
Reformat using new isort settings.

keyringctl:
Add `get_fingerprints_from_import_source()` to derive all fingerprints
of PGP public keys found in the import source.
Add `get_fingerprints_from_decomposed_dir()` to derive all fingerprints
of PGP public keys found in a directory structure holding decomposed PGP
packet data.
Add `get_fingerprints()` to derive a set of fingerprints of PGP public
keys provided through `get_fingerprints_from_import_source()` and
`get_fingerprints_from_decomposed_dir()`.
Change `convert()` and `convert_certificate()` to accept an optional set
of strings (`fingerprint_filter`) that may be used as a filter for
valid fingerprints when considering certifications.
Change `__main__` to call `convert()` when importing keys to packager or
main dir, providing `fingerprint_filter` which will attempt to look up
fingerprints in the source as well as the target.

keyringctl:
Add `derive_user_from_target()` to derive the username from an existing
public key in the target directory when importing (updates to) an
already known key.
Change `convert()` to either use a custom name override (if provided), a
username derived from target dir (if existing) or the file name of the
to be imported file as username.

Use black to format the file, isort to auto-sort all imports.
Remove commented code and (for now) ignore the high complexity in
`convert()` so that flake8 can be used.

keyringctl:
Change `persist_certifications()` to not attempt to read UID binding
signatures for a given UID, if it does not exist and instead output an
error message.

keyringctl:
Change `convert()` to create the target directory including parents.
Change `export_keyring()` to create the output directory and its
parents before outputting data into it.
Remove `keyring_import()` as its functionality is covered by using
`convert()` directly with different subcommands.
Change `__main__` to define `import-main` and `import-packager`
subcommands instead of `import` and to add an `export-keyring`
subcommand. Remove the explicit creation of target dirs (it is now
implemented in `convert()` and `export_keyring()`.
