P2P Key value storage, developed for Python 3.5 +

    Protocol is defined as:
    
    KeyReq (type = 5)
    | Type | SeqNum |        Key        |
    0         2     6              6 + length*2
    
    TopoReq (type = 6)
    | Type | SeqNum |
    0      2        6
    
    (Key/Topo)Flood (type = 7 or 8)
    | Type | TTL | SeqNum | Orig_IP | Orig_Port |      Info        |
    0     2      4        8        12          14               14+length*2
    
    Answr
    | Type | SeqNum |       Key        |
    0         2     6            6 + length*2

    Numbers are bytes, max length = 400.
