Replaced the use of the standard library trig functions with a LUT-based
implementation instead. The standard library implementations produce
more accurate results but the usage here doesn't need that. This ends up
saving nearly 7kB of binary size.
* PineTimeStyle
* Move GPL license header
* Add step count gauge - replaces heartrate in sidebar
* Enable 12/24h functionality
* Set step gauge outer to be white when step goal is reached
* Add font source file
* Move static needle_colors array to member variable
* Add documentation on generating a font
* Replace .ttf with Google version, add link to font page

* Retrieve and display bootloader version
- Display bootloader version on System Info screen
- Enable SPI flash sleep mode if bootloader version >= 1.0.0
* Wait for SPI flash to wakeup before starting OTA DFU
* update font with jetbrains mono v2.225 and the current converter
* added the tff file for JetBrains Mono to ensure everybody is using the same version

* add basic metronome app
* add bpb, tap to bpm, update widgets
* use event pressed for bpm tap
* move case statement break to the right place
* narrow bpm selection range, override touch events
* fix arc knob style
* re-enable sleeping in destructor
* Add the following compilation flags:
* -fno-exceptions and -fno-non-call-exceptions : disable exception handling
* -fno-rtti : disable run time type information (needed by dynamic_cast, for example)
These flags reduce the binary size by about 100KB!
Also, -fstack-usage generate debug info (not in final binary) to allow tools like Puncover to do a stack analysis.
* Remove unused CMake variables in CMake_nRF5x.cmake (duplicated in src/CMakeLists.txt).
Replace -O0 by -Og in DEBUG builds. This generates a smaller binary (small enough for the internal memory) that is debugger friendly.
* Navigation app:
- Renaming and reformatting according to coding conventions
- declare iconMap as constexpr and use char* instead of std::string
This reduces the flash usage from 424644B to 419344B (-5300B)!
* built timer app
* Style improvements
* making sure buttons stay hidden when the app is reopened and reappear after the timer runs out
* more sensible calculations of time deltas. eliminated that mysterious scaling factor
* changing the timer icon
