[Feature Request] Exclude keywords

[isabellaalstrom]

Is your feature request related to a problem? Please describe.
I watch several shows that's released every day. I would like to be able to exclude them from the sensor since I'm not really interested in when they're downloaded. For now I have solved this by adding an if statement before line 218 self.card_json.append(card_item)
that checks if card_item['title'] contains one of those keywords, but it would of course be good to have this as a config option. I will try to do this my self, in that case I will do a pr if you think this is a good idea.

Describe the solution you'd like
See above :)
