Description

Reported by @AlyaGomaa on the pycommunityid project:

https://github.com/corelight/pycommunityid/issues/8

The following flow produces the wrong community id value:
```
"src_ip": "fe80:0000:0000:0000:00d2:4591:568e:c3d1",
"src_port": 5353,
"dest_ip": "ff02:0000:0000:0000:0000:0000:0000:00fb",
"dest_port": 5353,
"proto": "UDP",
```

Suricata 7.0.0 reports `1:JpepHprmBz0RFdlLGhEMO4jAPvA` while Zeek and pycommunityid report `1:Ij3wBn8AhEgwlNMz41h3vXi0yL8`.

It appears there's a bug in Suricata around sorting of IPv6 addresses - will open a PR.
