Watch faces can now be selected at buid time. It's implemented in a similar way than the selection of user apps, using a list of watch face description that is generated at build time (consteval, constexpr)
1. Replace sprintf with snprintf, which is safer
2. An unsigned int or unsigned long int requires 11 bytes to print
(including the null terminator)
3. Use PRIu16 macro to print uint16_t
4. Format string "#%2d %2d:%02d:%02d.%02d\n" in
StopWatch::stopLapBtnEventHandler() requires at least 17 bytes.
The 16-byte buffer would clearly be overrun if sprintf were used.
This new algorithm calculates the number of degrees that the wrist has
rolled, and checks if that is above a threshold.
First it checks if the wrist is still enough for the acceleration values
to be considered mostly from gravity. It does this by calculating the
mean over the past 2 SystemTask loops, and checking that the variance
from that mean is below a threshold.
Then it calculates the angle the wrist is being held at, and calculates
the difference from the angle some time ago. If this difference is above
the threshold, it wakes the watch.
The accumulated speed was calculated by dividing first and multiplying
after, which results in more rounding errors than if you multiply first
and then divide. The values aren't big enough to overflow.
This commit changes the order for the notification struct fields to allow the creation of notifications using a string literal.
```cpp
NotificationManager::Notifiation notification {
"String literal with notification text",
42,
NotificationManager::Categories::SimpleAlert
};
```

* ShakeWake: Fixed instant wake after sleep issue in certain positions
Add lastX var to track the previous x acceleration for correct calculation of speed.
Reorder axes for clarity.

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).
Previously, the LVGL driver for the filesystem was initialized in the class FS. However, since 6f942e2, the order of the initializations was incorrect : the driver was initialized (FS::LVGLFileSystemInit()) before LVGL (LittleVgl.Init()), which means that the driver registration was probably dropped when LVGL was initialized.
The LVGL driver is now initialized in LittleVgl.Init(), which seems to make much more sense, since all LVGL drivers are initialized there. This way, we ensure that the initialization of the drivers is consistent.
