IPv6 support

Can you add this feature to bundle?
I made this changes to RedisDsn class in method parseDsn:

        if (preg_match('#^([^:]+)(:(\d+))?$#', $dsn, $matches)) {   //IPv4
            if (!empty($matches[1])) {
                // parse host/ip or socket
                if ('/' === $matches[1]{0}) {
                    $this->socket = $matches[1];
                } else {
                    $this->host = $matches[1];
                }
            }
            if (null === $this->socket && !empty($matches[3])) {
                // parse port
                $this->port = (int) $matches[3];
            }
        } elseif (preg_match('#^([^.]+)(.(\d+))?$#', $dsn, $matches)) { //IPv6
            if (!empty($matches[1])) {
                // parse host/ip or socket
                if ('/' === $matches[1]{0}) {
                    $this->socket = $matches[1];
                } else {
                    $this->host = $matches[1];
                }
            }
            if (null === $this->socket && !empty($matches[3])) {
                // parse port
                $this->port = (int) $matches[3];
            }
        }

If this is correct, add it to your repository plz
