Find the table row following the referenced table row in a secondary 64-bit integer index table

@brief Find the table row following the referenced table row in a secondary 64-bit integer index table @param iterator - The iterator to the referenced table row @param primary - Pointer to a uint64_t variable which will have its value set to the primary key of the next table row @return iterator to the table row following the referenced table row (or the end iterator of the table if the referenced table row is the last one in the table) @pre iterator points to an existing table row in the table @post *primary will be replaced with the primary key of the table row following the referenced table row if it exists, otherwise *primary will be left untouched
