AK: Fix IPv6 serialization on multiple '0' parts ending in a '0' part
This could happen if a sequence of '0' parts was followed by a longer sequence of '0' parts at the end of the host. The first sequence was being used for the compress, and not the second. For example, [1:1:0:0:1:0:0:0] was being serialized as: [1:1::1:0:0:0] instead of [1:1:0:0:1::]. Fix this by checking at the end of the loop if we are in the middle of a sequence of '0' parts that is longer than the current longest.
