Review comment:
@ssorj I think I now see what you meant, the `pn_delivery_tag` is a type
alias for `pn_bytes_t`, and the reasonable types for in in C++ are std::string
or std::vector<uint8>. So, one of the two following functions should be used
instead of `make_wrapper`
https://github.com/apache/qpid-proton/blob/8ddf5399013b02f1fd13bda3fee7886bd48a98be/cpp/src/types_internal.hpp#L58-L59
Both make a copy of the data, which simplifies things.
