v6.15.0 introduces breaking changes with the new server.listen unix socket method

[tayler-king]

Prior to v6.15.0, server.listen(port, host) would accept a string for the port, such as "8080".

With v6.15.0 it now assumes that port is a unix socket if it is a string. This is a breaking change and should be treated as such.

Possible hotfix if you don't want to introduce a breaking change is to check if the host argument has been passed, rather than checking if port is a string, or check if port is castable to a number.

This has been fixed in the recent v6.15.1 update and casts first argument strings to the numeric port range before treating it as a unix domain socket path.

With that said, The types and documentation has always dictated the port argument should be a number and acceptance of a string was a side-effect of uWebsockets.js not enforcing its types.
