Userscript to redirect Lemmy links to Kbin magazine format

Hi all! Here's a script I threw together to fix a little annoyance that was making Kbin a bit frustrating given how much is on the bigger Lemmy instances. Any shortlinks in the format of !topic@domain become /m/topic@domain and thus open correctly on your kbin instance.
It only runs on kbin.social at the moment but I will gladly add other kbin sites if there's a list somewhere.
