Windows 0.0.0.0:53 bind error

[chmichael]

I am getting on windows with the latest version:
cound not bind to UDP: 0.0.0.0:53, Only one usage of each socket address (protocol/network address/port) is normally permitted. (os error 10048)

If the port is not already opened, it may be an address reuse issue, but this is not covered in the update.

smartdns-rs/src/server/net.rs

Line 31 in d9b544b

sock_ref.set_reuse_address(true)?;

@mokeyish
According to this article Hyper-V is using the 53 port and can be shared: (I have Hyper-V installed)

btw you're reuse the address not the port too so I tried to add sock_ref.set_reuse_port(true)?; but i got an error on compiling:

    --> src\server\net.rs:73:12

73 |         sock_ref.set_reuse_port(true)?;
   |                  ^^^^^^^^^^^^^^ method not found in `SockRef<'_>`

It maybe not support on Windows

As you can see the port 53 port isn't used. btw i ran another DNS Server app and it's working.

Again i can use other windows dns servers without problems and also previous versions of smartdns worked.
Seems some depedancy upgrade or change caused this.
