disable SIO_UDP_CONNRESET behaviour for UDP

[silbinarywolf]

• Disable SIO_UDP_CONNRESET behaviour for UDP sockets
• Add test to catch error error.Unexpected: GetLastError(10054): An existing connection was forcibly closed by the remote host. if SIO_UDP_CONNRESET disable code is not present.

Example of error thrown without this PR:

error.Unexpected: GetLastError(10054): An existing connection was forcibly closed by the remote host.
