Drive everything through the ESP32. This also eliminates the level shifter and all UARTing.
Also an important fix to our Steinhart-Hart implementation.
Completes the implementation of mqtt, pwm, and tach for the XTOP Dual D5 pumps. One PWM input is supported, and sent to both pumps. Both tachometers are read, and published to MQTT.
The Heltec display now shows the XTOP values and the ambient temperature. Support a DS 1wire themosensor for ambient temperature.

Several fixes to sensor scripts.
