German determiners

[DCSaunders]

In src/languages/gendered_article.py, the German masculine accusative determiner "den" is included, but commented out. Is there a reason for not allowing it?

It seems to have a small impact on scores, but does cause a few sentences to be wrongly flagged as having fewer than 2 determiners.

Same in src/languages/german.py, although this dictionary doesn't seem to be used.
