Status not set when processing 367_22 in ais8_to_pydict in ais_py.cpp.

[andyvan-trabus]

I noticed while added processing for 367_33 that the following lines call ais8_367_22_append_pydict but don't set status to AIS_OK, which means that the message processing will appear to fail:

case 367: // United states.
switch (msg.fi) {
case 22: // USCG Area Notice 2012 (v5?).
ais8_367_22_append_pydict(nmea_payload, dict, pad);
break;
