AnyMotion example using SensorQMI8658.

This example demonstrates how to:

• Configure any-motion detection
• Set motion detection thresholds and time window
• Handle any-motion detection callbacks

@important AnyMotion Notes:

• Any-motion triggers when any significant acceleration is detected.
• The detection threshold and time window can be tuned for sensitivity.
• Uses hardware interrupt callback for low-power operation.

@usage Connect the QMI8658 sensor via I2C or SPI and upload this sketch. Open the Serial Monitor to see any-motion detection events.
