Errors on options 150 and option 81

[tmittelstaedt]

Get assertion failure when

dhcptest-0.0-win64 --query --request 150

And 81 Unknown when

dhcptest-0.0-win64 --query --request 81

Option 150 is commonly used for VoIP PBX servers. Both Cisco and Polycom use it (among others)

Option 81 seems to be handed out by OpenWRT's DHCP server it lists as (Client FQDN) and it may be handed out by other DHCP servers. While that does not list an assertion error it halts processing on the received DHCP packet
