[FEAT] Forcing IPv6 in output by default

[Disinterpreter]

Wanted features:

At the moment, doing a fastfetch command i've get only my IPv4 address with a subnet.
I think it is little wrong, IPv6 must be preferred as in all services.
So I suggest to change network output:
IPv6 GUA on interface (if it exist 2000::/3)
IPv6 ULA on interface (if it exist fc00::/8)
and after that IPv4 address.

and making a flag for link-local(fe80::/10) like --localip-show-link-local

Motivation:

IPv4 actual protocol, but it gonna be old in future, we should force IPv6 output everywhere for next generation of engineers.
