Propagate exceptions raised by the user's packet callback

Avoid calls to the packet callback during queue unbinding

Raise an error if a packet verdict is set after its parent queue is closed

Add type hints

Remove the Packet.payload attribute; it was never safe (treated as a char* but not NUL-terminated) nor documented, but was exposed in the API (perhaps inadvertently).

Improve usability when Packet objects are retained past the callback

Add Packet.retain() to save the packet contents in such cases

Eliminate warnings during build on py3
