add option in ofxTCPSettings to allow TCP_NODELAY

I have an OF app that is sending X number of bytes to an ESP32 client at 25fps.
If the framerate is above 5fps the server sometimes joins data sends in to a single transmition. So instead of receiving X number of bytes. I get a multiple like 2x or higher in faster transmition rates.
This occurs because TCP has TCP_NODELAY Option enabled by default. This may not be an "issue" for everyone but was definitely a problem for my application.
I resolved this by adding the following lines of code into the Create() function in ofxTCPManager.cpp when the tcp connection is being made:

int enable=1;
if (setsockopt(m_hSocket,IPPROTO_TCP,TCP_NODELAY,(char*)&enable,sizeof(int))< 0)	
{
	//adedd to disable no delay
}

bool ofxTCPManager::Create()
{
	if (m_hSocket != INVALID_SOCKET) return(false);
	m_closing = false;
	m_hSocket = socket( AF_INET, SOCK_STREAM, IPPROTO_IP);
	int enable=1;
	if (setsockopt(m_hSocket,IPPROTO_TCP,TCP_NODELAY,(char*)&enable,sizeof(int))< 0)	
	{
		//adedd to disable no delay
	}
	bool ret = (m_hSocket != INVALID_SOCKET);
	if(!ret) ofxNetworkCheckError();
	return ret;
}

Start by locating ofxTCPSettings and the socket creation code in ofxTCPManager.cpp, especially Create(), then read how TCP connection options are currently configured. Define how the TCP_NODELAY setting should be exposed and what its default should be. Done means the option can control the socket behavior described in the issue and the connection setup remains valid.
