Suggestion: Extended AllowedIPs syntax

[Posegga, Joachim]

I would very much appreciate a way to exclude subnets from being routed through a wg tunnel. Would be much more convenient than changing the system's routing table by hand, e.g. if you want to keep connectivity to your local subnet when establishing a tunnel for 0.0.0.0/0.

I find the AllowedIPs CIDR format difficult to grok. What if Wireguard allowed...

 +IP/mask - add a range
 +IP-IP - add a range
 -IP/mask - remove a range
 -IP-IP - remove a range

Multiple terms would be interpreted left to right

i.e.

AllowedIPs: +1.2.3.0/24 -1.2.3.1-1.2.3.10 -1.2.3.255
