This new implementation of the weather feature provides a new BLE API and a new weather service.
The API uses a single characteristic that allows companion apps to write the weather conditions (current and forecast for the next 5 days).
The SimpleWeather service exposes those data as std::optional fields.
This new implementation replaces the previous WeahterService.
The API is documented in docs/SimpleWeatherService.md.
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)
Building with a TARGET_DEVICE set to any of the P8 variants' names
caused the build to fail, because they contained hyphens.
The build defines a macro `TARGET_DEVICE_$VARIANT`, which fails if
`$VARIANT` contains a hyphen.
A list of "user applications" is built at compile time. It contains all the info needed to create the application at runtime (ptr to a create() function) and to display the app in the application menu. All applications declare a TypeTrait with these information.
When a new app must be loaded, DisplayApp first check if this app is a System app (in which case it creates it like it did before). If it's not a System app, it looks for the app in the list of User applications and creates it if it found it.
Those changes allow to more easily add new app and to select which app must be built into the firmware.
Switch to C++20 (and fix a few issues in SpiMaster.cpp and Watchdog.cpp.
* change background image to widgets
This commit removes the background image for the WatchFaceAnalog and replaces it with lvgl widgets. It aims to keep the original look.
* remove comments and background image

LVGL supports custom implementation of malloc() and free() so using pvPortMalloc() and vPortFree() is just a matter of setting the right variables.
Other libraries (NimBLE, LittleFS) and InfiniTime code (new) call malloc() and free() from stdlib. InfiniTime now provides the file stdlib.c that provides a custom implementation for malloc(), free(), calloc() and realloc(). This ensures that all calls to the standard allocator are redirected to the FreeRTOS memory manager.
Note that realloc() is needed by NimBLE.
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).
Replace separate SettingSetDate and SettingSetTime with a combined screenlist.
Add DotIndicators. Similar to PageIndicator, but for use when separating screens instead of pages of a list.

Removed/simplified some generator expressions that had more repeated
elements than they needed to. Extracted some repeated sets of options
into separate variables as well.
This configures Nimble to enable the HFCLOCK and other
Bluetooth peripherals only when needed, but 1500 us in advance.
This time is recommended by the Mynewt docs.
