The project was archived in 2021, and we can fairly easily replace it
with some ctypes code to call getifaddrs ourselves.
Be willing to fall back to netifaces (with a warning) in case getifaddrs
is not available, but I'm fairly certain it will be for all platforms we
support.
Could maybe use some more testing on big-endian arches / BSDs, but an
attempt was at least made at supporting them.
