Add support for A02YYUW Waterproof Ultrasonic Sensor #45
For battery operation, the sensor power supply must be switched to reduce power consumption in sleep mode.
For integration of multiple sensors, the outputs could be connected with a multiplexer (e.g. 74HC151 8-Line To 1-Line Data Selectors/Multiplexers or 74HC153 Dual 4-Line To 1-Line Data Selectors/Multiplexers) to the ESP32 UART RX input.
