Modulino Buzzer not compatible with Nano ESP32 board over I2C

[ArsenHereaux]

The Buzzer Modulino does not respond to tone commands correctly when passed from an Arduino Nano ESP32 over I2C.

Configuration:

• Example sketches: "Buzzer_Basic" and "Simple_melody"
• Modulino connected via its QWIIC to Nano ESP32's 3.3V, GND, A4 (SDA), and A5 (SCL) pins

Results:

• Tone commands are silent when frequency is non-zero
• Tone commands are a high-pitch frequency when frequency is zero
• Tone commands appear to respond correctly to duration

@facchinm it happens because tone is already defined in esp32 core
