[FEATURE] News sentiment analysis #4

Maybe https://huggingface.co/ProsusAI/finbert (or another model that can be run on the cpu) can be implemented to extract a sentiment values from news articles/headings.
This could be used to color the news articles in the news overview (e.g red -> bad, green -> good). This could maybe also be used to chart a "average daily news sentiment" over the last N days.
