Adds hollodotme/fast-cgi-client to list of event libraries

[hollodotme]

Fast CGI Client calls PHP scripts directly through the php-fpm socket (network or unix domain) and therefore implements the FastCGI protocol. Requests can be sent synchronously or asynchronously. In case of asynchronous requests it is possible to get the responses in various ways, blocking and non-blocking, ordered by request-order or reactive ordered by response time of the requests. It allows non-blocking loop integration and callbacks for responses and/or failures.
