Checkpoint Photographs Update

This change pertains to checkpoint photograph delivery requirement. The current requirement is for checkpoint photographs to be delivered embedded in a single PDF document. This modification allows for delivery as individual photographs in sub-directories to maintain image quality and allow for redaction of single images, if necessary. 

Status of this revision: Published in Lidar Base Specification 2021 rev. A

Please Note: This change only provides for an additional delivery option--no other requirements for checkpoint photographs are changed.
