       The  bson_iter_recurse()  function  shall initialize child using the embedded document or array currently
       observed by iter.

       If there was a failure to initialize the iter, false is returned  and  both  iter  and  child  should  be
       considered invalid.

       This should only be called when observing an element of type BSON_TYPE_ARRAY or BSON_TYPE_DOCUMENT.

       • iter: A bson_iter_t.

       • child: A bson_iter_t.

       If  iter observes an element of type BSON_TYPE_ARRAY or BSON_TYPE_DOCUMENT, then child is initialized and
       the function returns true. Otherwise, the function returns false and child is invalid.
