Some installations might need to add further images
to records imported from ThüCAT.
The records are now extended to support adding images by editors.
The images are not touched during import.
The images are also ignored during clean ups,
the editor is in full control.
This feature for now is only added to tourist attractions by default.
The feature is implemented in a way that all objects extending the
``WerkraumMedia\ThueCat\Domain\Model\Frontend\Base`` class are usable
by adding an ``editorial_images`` field to their table.
Those are handled the same way,
the entity is skipped and errors are logged.
That way further entities can be imported
while only none working entities are skipped.

The command is also available as scheduler task.
This finally allows to regularly execute imports.
This also allows to import from CLI context
with differently configured timeouts.
