New implementation of the heart rate sensor data processing using a frequency based PPG algorithm. The HRS3300 settings are fine-tuned for better signal to noise at 10Hz. The measurement delay is now set to 100ms. Enable and use the ambient light sensor. FFT implementation based on ArduinoFFT (https://github.com/kosme/arduinoFFT, GPLv3.0).
