Support for Port range or all ports (0-65535) Forwarding

[Shadowu410]

Is your feature request related to a problem? Please describe.
Currently one lb rule only serve one port, and I noticed that a macro definition in the code limit total lb rules number to be 1024.

Describe the solution you'd like
Support for port range or all ports forwarding in one single lb rule. For example, loxicmd create lb 88.88.88.1 --tcp=3000-5000:12345 --endpoints=192.168.70.3:1 --mode=fullnat

Describe alternatives you've considered
nftables is considered, configration likes below:
chain prerouting {
type nat hook prerouting priority dstnat; policy accept;
iifname eth0 ip daddr 88.88.88.1 tcp dport 3000-5000 dnat ip 192.168.70.3:12345
}
