Problem with the XML conversion of the GXDLMPushSetup.java class

Greetings!

A problem occurs in the XML conversion of the GXDLMSPushSetup.java object, when the attribute number 3 (send_destination_and_method) is not a printable string.

This occurs because in the setValue() method of the GXDLMSPushSetup.java class a non-printable value can be assigned to the line 414:

setDestination(new String((byte[]) tmp.get(1)));

A hex string assignment is suggested:

setDestination(gurux.common.GXCommon.bytesToHex((byte[]) tmp.get(1)));
