Subject: [PATCH] Add reset() function for complete sensor reset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add reset() function that combines OTP memory reboot and algorithm reset
- Integrate reset() call into begin() initialization sequence after isConnected()
- Ensures clean sensor state before applying configuration settings
- 5ms delay for proper sensor reset timing
