Full Changelog: v12.0.1...v12.1.0

This release removes all scanning around behaviors, stream behaviors, and pre/post processors. That proved too problematic so you MUST register each of these explicitly with the appropriate registration methods inside AddMediatR. This also ensures that the order of behaviors and pre/post processors reflects the explicit order of registration. With the scanning approach, you couldn't control the order.
