Provide control over the source of the timestamp #25

This allows selecting between getting the timestamp from the camera or from the system running the IOC.

The system timestamp is obtained from the aravis buffer which was saved on the reception of the first packet of the image, this is more precise than timestamping after receiving the full frame.

The reason why this change is needed is because we have certain cameras in which PTP doesn't work and using the system timestamp in the aravis buffer would be good enough for our application.

Tom suggested renaming the record so that it matches ADVimba's, I've amended the commit

Given that my use-case turned out to work fine using the epics timestamp, I'm closing the PR
