Winsock error

[gvanem]

This seems like a cool project, but I'm not sure about the Windows support. Since for any configuration, I get this error:

....
  File "F:\gv\Python310\lib\site-packages\pytak\client_functions.py", line 80, in create_udp_client
    reader = await dgbind((host, port))

    transport, protocol = await loop.create_datagram_endpoint(

    sock.bind(local_address)
OSError: [WinError 10049] Cannot assign requested address.

10049 == WSAEADDRNOTAVAIL. Ref: https://learn.microsoft.com/en-us/windows/win32/winsock/windows-sockets-error-codes-2

With some added trace, I see the address in pytak/asyncio_dgram/aio.py is ('239.2.3.1', 6969) and family == 0 (AF_UNSPEC).

Even after adding COT_URL = udp://239.255.255.250:6969 to my config.ini, it fails.
