Dive photos are copied to the photos directory on export. The photos
section appears only if photos exist.
C++ helper functions are added to copy images to the photos directory,
Additionally the photos directory must be passed as a parameter to the
write_one_dive function to save photos to it. Some options structure may
be needed instead of passing many arguments.
