Fix for Hrs3300 PR about Atomic HRS reads:
https://github.com/InfiniTimeOrg/InfiniTime/pull/1845
We use `std::begin` and `std::end`, but we don't include one of the
headers that define those functions.
See https://en.cppreference.com/w/cpp/iterator/begin for a list of
headers that define `std::begin` and `std::end`.
Starting with GCC 14 this leads to a compilation error presumably
because they cleaned up their headers.
Fix code by inlcuding `<iterator>`

- 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

Put the HRS3300 to sleep mode when InfiniTime is going to sleep. This change reduces the power consumption by 130µA when the heart rate sensor is disabled.

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).

Also add configuration options only available in 13 and 14.
Fixes warning about -fstack-usage in clang-tidy check.

Don't use relative imports like `../foo.h` as those depend on the
relative position of both files. Rather than that use imports relative
to the `src` directory, which explicitly is part of the include
directories.
