Distinguish between types of unsubscribes on the email performance page

It would be helpful if the email performance page differentiated between “unsubscribed from all emails” and “unsubscribed from a specific subscription type”. Currently, those are counted together, which can make it seem like we’ve lost contacts who actually just opted out of one kind of email.

This could also potentially be useful for segmenting purposes, so people don’t accidentally sunset contacts who are still subscribed to other subscription types.
