Graphics & rendering - Implement `binfont-module` to generate bitmap fonts on the device itself - Remove lodepng support from LVGL library and create `Modules/lodepng-module` to make the feature re-usable in non-LVGL apps too. Add binding functions for LVGL support. - Implement large icons for boot screen (Tactility and USB logos) - Remove unused asset files in `Data/` Boot - Split up `Tactility.cpp` and its `run()` function into various `Init*.cpp` files. - Re-implement `Boot.cpp` app as non-LVGL app - Boot app now has a `BootSequence.cpp` for the init code. - LVGL is now started when the Boot app finishes - Move more init logic into Boot app BLE - Don't allocate scan result buffers unless BLE is on - Allocate scan results in external memory if possible UX & UI - USB Settings app: remove border from the button container
