[Feature request] ability to listen on multiple addresses/ports #1

Here I use a network namespace sandbox in which a DNS port is forwarded to a subnet in this way:

iptables -t nat -A PREROUTING -i subnet -p udp -s 10.0.0.2 -d 10.0.0.1 --dport 53 -j DNAT --to-destination 10.0.0.1:1053
ip6tables -t nat -A PREROUTING -i subnet -p udp -s fd00::1 -d fd00::1 --dport 53 -j DNAT --to-destination [fd00::1]:1053

The peer will have a UDP port 53 available in the IPv4 and IPv6 address for DNS resolution.

I could just set the addresses of bind IP in zdns to [::]:1053, but it would listen on all ports of my machine, such thing is a undesirable behavior.

An option in zdns to listen on multiple addresses/ports would be nice in this scenario.
