Allow for deleting associated cards when deleting a dataset, or in the card view of the dataset. Right now, the only action we can do when looking at which cards are powered by a dataset is to switch them to a different dataset. If we no longer need the cards and want to delete the dataset that powers them, there is no easy way to do that right now. Another one of my requests also mentions the ability to filter to cards based on the dataset that's powering them in the Admin view, which would also be really helpful.
