Subject: [PATCH] Add auto-configuration for highest precision and new
 simpletest example
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Configure begin() for highest precision (128x oversampling, 200Hz rate)
- Enable temperature and pressure ready interrupts automatically
- Add simpletest example with data-driven updates
- Update library.properties with Adafruit Unified Sensor dependency

+/*!
+ * @file simpletest.ino
+ *
+ * A simple test for the SPA06_003 pressure and temperature sensor.
+ * This example shows basic pressure and temperature readings using the sensor.
+ * 
+ * The begin() function automatically configures the sensor for:
+ * - Highest precision (128x oversampling)  
+ * - Highest sample rate (200 Hz)
+ * - Continuous measurement mode
+ *
+ * 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.
