Fixed server and client examples for IO::Socket::Async (#1628)
Fixed server and client examples for IO::Socket::Async (#1628)

* IO::Socket::Async server example using heredoc

and maybe more clearer for newcomers

* IO::Socket::Async client example tweaks

Couple of tweaks:
- There are issues with libuv when it defaults ipv6 when using localhost name. We can workaround that just using 127.0.0.1 instead of localhost name.
- Added newline for print
