Un-decodable 0x09 network_management_installation_maintenance command

[Jean-Francois Cloutier]

I just saw this

19:44:57.314 [error] GenServer #PID<0.2950.0> terminating
** (FunctionClauseError) no function clause matching in Grizzly.ZWave.Decoder.from_binary/1

What's interesting is that I cannot find a documented command 0x09 for CC 0x67 (:network_management_installation_maintenance)

Here's some more information about that binary:

1. The 9 means S2 resynchronization event
2. The 8 is the node number for this message.
3. The 0 is the reason. It's SOS_EVENT_REASON_UNANSWERED. There's only one reason defined currently.

Here's some text about it:

/** 
 * SOS_EVENT_REASON_UNANSWERED means that a Nonce Report with Singlecast-out-of-Sync                                                                                                                                                                    
 * (SOS) = 1 has been received at an unexpected time and no response was sent.
 *  
 * A Nonce Report SOS is considered expected and no SOS_EVENT_REASON_UNANSWERED will be emitted in these case:
 *    1) libs2 is in Verify Delivery state and receives a Nonce Report SOS from the
 *       node being delivered to and will re-transmit the encrypted message
 *    2) libs2 has already re-transmitted and receives a second SOS from the node being transmitted to
 *       during Verify Delivery timeout. A \ref S2_send_done_event() with
 *       status=TRANSMIT_COMPLETE_NO_ACK will be emitted instead.
 *
