+Sets the socket timeout used by the client. This determines how long the client
+will wait for incoming data when it expects data to arrive - for example, whilst
+it is in the middle of reading an MQTT packet.
+
+By default, it is set to `15` seconds - as defined by the `MQTT_SOCKET_TIMEOUT`
+constant in `PubSubClient.h`.
