NAT64/DNS64 shows up as IPv6

See original GitHub issue

What steps will reproduce the problem?
1. Set up network with IPv6 only and NAT64/DNS64 for reaching IPv4 internets
2. Load some sites with just A records
3. Profit!

It would be nice if the plugin would de-synthesize NAT64 and show it as IPv4 
connections. Now EVERYTHING shows up as IPv6 here. Sort of but not really 
misleading, though very annoying ;-)

Application/OS level NAT64 detection is kinda up in the air at the IETF still I 
think, but desynthesizing the "well known" NAT64 prefix 64:ff9b::/96 back into 
displaying as IPv4 would help a lot, even if its just changing the icons back.

There is now a known host in DNS for this purpose: ipv4only.arpa. If you get an AAAA back from this, you know you’re behind NAT64.

IPvFox had this functionality before it went unmaintained: https://github.com/Dagger0/IPvFox/commit/4dd97947e0e6ef8296c5321354ea2e9ea41bffb1 Dunno if any of that code can be repurposed into a WebExtension.

How about “(4)” (4 in brackets)? Or a green 4, or a red 6?

All three of them sound sensible to me
