I'm writing daemons in Nim, and I fail to get it working with IPv6
My nim code uses a socket created by `newAsyncSocket()` from `asyncnet` and
uses `bindAddr` to bind the socket to an address specified on the command-line.
The bind address is specified in the form of a hostname and when the hostname
represents an IPv6 only address (except for localhost, I don't know why) it
fails.
I get:
/home/runner/work/stalwart-gw/stalwart-gw/src/stalwart_gw.nim(245)

Reading at the code `bindAddr` is calling `getAddrInfo` with the socket domain
for the address family. here I don't know the domain of socket in advance, it
can neither be AF_INET nor AF_INET6 and it depends on the hostname. A proper
value would be AF_UNSPEC which is not possible.
Should I resolve the address family in advance before creating the socket, and
depending on the actual address family create the socket with the proper domain?
