Changing INT and RST pins to A4/A5

-Changing the pins used int he example. A4/A5 are available on both the ESP32 IoT Redboard and the SAMD51 Thing Plus. This allows the same example sketch to work with both products (and others that have A4/A5, which is pretty common).

   Hardware Connections:
-  Plug the sensor into IoT RedBoard via QWIIC cable.
