This adds a API on our UART drivers for getting the timestamp of the last input bytes. This is then used for vision processing to constrain the latest possible time the message arrived, which makes the timestamping of vision messages more accurate.

from a chat with @WickedShell it sounds like he would prefer more investigation and testing into the GPS changes so perhaps we should pop the last commit off before merging for now.
