Calculating scores from .csv feature

From chat:

it would be great if we could have a very simple, internal page where the user would upload a csv - just one column of addresses, and the page would fetch the scores for those addresses (display them in a table also) from the db, recalculate if the score is not present or old (<1day), and also a button to download this csv again, this time with scores
