Field formatter is incompatible with smart dates provided by smart date module

This patch needs a lot of work
$this->smartDateElements($items, $langcode);
but methode smartDateElements has only $items without $langcode;
and errors with phpcs
395 | ERROR | [ ] Missing parameter comment
395 | ERROR | [x] Data types in @param tags need to be fully namespaced
397 | ERROR | [ ] Description for the @return value is missing
I think smartDate must have a service to get the date and end date, it must use the service if it exists
