       The  bson_iter_find_w_len()  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.

       • keylen: An integer indicating the length of the key string.

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