[MODULE] - German sentiment classifier

[LeonardPuettmannKern]

Please describe the module you would like to add to bricks We have some sentiment classification bricks, but only for English. It would be cool to have one for different languages, for example, German.

Do you already have an implementation?

Additional context This model could be helpful: german-sentiment-bert

I also found the package germansentiment using BERT itself, which I wanted to try out. :)

The output of the except statement needs to be changed, as it does not conform with the structure of refinery.
