Hush port scanner

Browse Source 
I wrote this simple port scanner in 5 minutes to verify if 3rd party Hush notary seeds
from https://github.com/KomodoPlatform/dPoW/blob/master/iguana/3rd_party
were running properly.

Currently they are all down.

$ cat contrib/notary_seeds.txt | ./contrib/hush_scanner
HOST   P2P  RPC
103.6.12.117 DOWN DOWN
95.213.238.99 DOWN DOWN
77.75.121.139 DOWN DOWN
139.162.45.144 DOWN DOWN
152.89.105.66 DOWN DOWN
152.89.104.58 DOWN DOWN
5.53.120.34 DOWN DOWN
139.99.208.141 DOWN DOWN
