As the retrieval of citations heavily depends on the keys, it would be great to have a check when parsing the file for duplicated keys. In such a case, no export should happen.

It checks for a duplicate key and prints a message so that the user can resolve it.
Maybe we should change the key to an alias if the title is not the same?
