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).
Prevents reading uninitialised memory if notification gets cut off due
to being more than 100 chars. The last character is assumed to be \0, but
it is actually uninitialised.
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.
Add linear approximation class and use it to better model the non-linear
discharge curve of the battery.
Changed the minimum voltage level to 3.5V and the maximum to 4.18V. For
reference the maximum observed voltage is 4.21V during charging.
