Update adafruit_espatcontrol_socket.py

I got error when using adafruit_espatcontrol_socket.py and  adafruit_minimqtt  when I use port 1883 for MQTT, it is due to connection type is not defined for port 1883

Traceback (most recent call last):
  File "code.py", line 117, in <module>
  File "/lib/adafruit_minimqtt/adafruit_minimqtt.py", line 447, in connect

RuntimeError: Connection type must be TCP, UDL or SSL

I propose to add conntype TCP for port 1883
