How to configure device timestamping?

[stephen-cpr]

I'm using a GQ7 and would like the driver to output IMU data based on the internal (presumably GPS time sync'd) clock, not the ROS time when the packet was received. It looks like in the past there was a 'use_device_timestamp' parameter you could configure, but this has since been removed. Is there still a way to do this?

It seems like we should be able to add that parameter back, and just have that option be read in the updateHeaderTime method. The GPS timestamp is already being passed into that method, but just isn't being used.
