Speed radio numpad hot keys

Great idea. In fact I recall you pushing the most cursed PR the other day, presumably on accident while trying to implement this. But as I recall, your PR specifically listed as a reason, "So when I am being murdered I can easily out them on radio". So your statement of acting like "how does this make antag callouts better?" seems weird, knowing that you yourself said that's why you wanted it in the game in your PR.

Nevertheless, the QoL part of it stands. It's just convenient to have a button assigned to different radio channels.
