DLR can be in clear text in the deliver_sm

[Mario San Vicente]

Hello Everybody,

I have noticed that when a dlr is received and deliver by jamind using smpp, it is passed from clear text and passed in bytes format.
I have investigated and understanf the RabbitMQ needs to use bytes but

Whats about changing at the end, when the deliver_sm packet is written.   I have been looking the callback function, when the queue is to be consumed,  or when dlr is to be published on the dlr.py  or content.py, but not working.   

NOTE: When text is passed to RabbitMQ it crashses,  so the change need to be when it is send in smpp.  If posibble.

showing when it is received in clear text, and change to bytes.
