six Network Layer messages should be implemented

[duffy-ocraven]

There are six Network Layer messages: X'00': Who-Is-Router-To-Network X'01': I-Am-Router-To-Network X'02': I-Could-Be-Router-To-Network X'03': Reject-Message-To-Network X'04': Router-Busy-To-Network X'05': Router-Available-To-Network

which are in common use, and two more defined, which are deprecated: X'06': Initialize-Routing-Table X'07': Initialize-Routing-Table-Ack

These are at network level, thus below, so differently encoded from any APDU.
