IPv6 randomization

[badbadmonkey]

Could you allow a feature for "Addresses" to permit randomization for IPv6 addresses in the interest of privacy.

Using Wireguard client forces selection of a /128 IPv6 address which does not change, with obvious privacy implications, ironically for a VPN.

Ideally you could set e.g. a /64 address space that matches the server "Allowed address" and rotate the client address on a specified schedule, or per connection.

Hi, as this functionality would need to be created in WireSock, I'll @wiresock to see if Vadim has any thoughts on this.
