- Combine the reading of all `HRS3300` registers into one I2C read so data is not partial
- Downsizes both HRS and ALS to 16bit as the sensor does not generate larger than
16bit values in its current configuration
- Increasing the resolution by 1 bit doubles the sensor acquisition time,
since we are already at 10Hz we are never going to use a higher resolution
- The PPG algorithm buffers for ALS/HRS are already 16bit anyway
- Remove functions for setting gain / drive that are unused throughout the codebase
- Calculate constants with constexpr
