Enhancement of "redirect" function, adding support for MacOS

Added the function of "MacOS" FreeBSD firewall traffic forwarding and resolving destination address
example:
"inbounds": [
{
"listen": "127.0.0.1",
"port": 1122,
"protocol": "dokodemo-door",
"tag": "dokodemo",
"settings": {
"network": "tcp",
"followRedirect": true,
"userLevel": 0
},
"streamSettings": {
"sockopt": {
"tproxy": "Redirect"
}
}
}
]
