Added Who-Is-Router process for Notification Class recipient unknown router addresses. (#1243)

Browse Source 
* Added Who-Is-Router-To-Network process in basic Notification Class when recipient address is missing the router MAC address.

* Added buffer_length parameter to octet string buffer decode functions

* Fixed BACnet address handling for I-Am-Router address updating the recipient list address for the next hop router.

* Changed VMAC encoding and decoding to use octet string buffer API to reduce stack RAM.
