Add unified sensor API example and apply code formatting

- Add sensorapi example demonstrating Adafruit Sensor interface
- Shows sensor specifications and metadata from datasheet
- Uses sensors_event_t structure for standardized readings
- Includes timestamp information for data logging compatibility
- Apply clang-format to ensure consistent code style

+/*!
+ * @file sensorapi.ino
+ *
+ * Demonstrates using the SPA06_003 sensor with Adafruit's Unified Sensor interface.
+ * This example shows how to get sensor information and read values using the
+ * standardized Adafruit Sensor API, which allows easy integration with other
+ * sensor libraries and data logging systems.
+ *
+ * The begin() function automatically configures the sensor for:
+ * - Highest precision (128x oversampling)
+ * - Highest sample rate (200 Hz)
+ * - Continuous measurement mode
+ * - Interrupt-based data ready detection
+ *
+ * Designed specifically to work with the Adafruit SPA06_003 Breakout
+ * ----> https://www.adafruit.com/products/xxxx
+ *
+ * These sensors use I2C to communicate, 2 pins are required to interface.
+ *
+ * Written by Limor 'ladyada' Fried with assistance from Claude Code
+ * for Adafruit Industries.
