This records the offset into the parent file where the heading was found.
Syntax
void truxton_exif_set_heading_offset( uint64_t exif_handle, uint64_t offset );
Parameters
exif_handle
This handle comes from calling truxton_exif_create() or truxton_file_create_exif().
offset
The offset into the file where the data began.
