       The  bson_iter_find()  function shall advance iter to the first element named key or exhaust all elements
       of iter. If iter is exhausted, false is returned and iter should be considered invalid.

       key is case-sensitive. For a case-folded version, see bson_iter_find_case().

       • iter: A bson_iter_t.

       • key: A string containing the requested key.

       true is returned if the requested key was found. If not, iter was exhausted and should now be  considered
       invalid.
