sort out more specifics and mark the less specific covering them in a way

that the resulting rule allows more specifics. i. e.
10.0.0.0/16, 10.0.1/24, 10.0.128/17 -> prefix 10.0.0.0/16 prefixlen <= 24
implementation: sort prefixes per AS by address family, prefix, prefixlen.
for every entry, check wether the prefix with the previous entry's mask
applied matches the previous entry's prefix & mask. Only move the previous
pointer forward if not so. Fill the holes we create in the process on the
fly; shrink the array afterwards.
shrinks the generated filters for our AS from over 100k to under 20k lines.
