Look up IP addresses by prefix at each mask length (closes #48)

Looking up an address read every IPv6 live route and, for IPv4, about half of the range index. Both families now look the address's prefix up at each mask length, longest first, on the prefix index: at most 33 or 129 indexed lookups, however many routes are live. The feed sends IPv6 withdrawals uncompressed but announcements compressed, so the prefix handler now stores every prefix in the text form net/netip prints, the form the lookup builds. IPv6 withdrawals now remove their routes. The IPv4 range columns, their index and the code that fills them are removed, and so are the unused GetASInfoForIP lookups. Model: opus-5-5
