 *
 * Demonstrates using the SPA06_003 sensor with SPI interface.
 * This example shows both hardware and software SPI configurations.
 *
 * 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 support both I2C and SPI interfaces.
 * For SPI connections:
 * - CS   -> pin 10 (or any digital pin)
 * - MOSI -> pin 11
 * - MISO -> pin 12
 * - SCK  -> pin 13
