## New features
- Implemented support for app packaging in firmware and `tactility.py`: load `.app` files instead of `.elf` files. Install apps remotely or via `FileBrowser`.
- Ensure headless mode works: all services that require LVGL can deal with the absence of a display
- Service `onStart()` is now allowed to fail (return `bool` result)
- Added and improved various file-related helper functions
## Improvements
- Completely revamped the SystemInfo app UI
- Improved Calculator UI of internal and external variant
- Fix Chat UI and removed the emoji buttons for now
- Fix for toolbar bottom padding issue in all apps
## Fixes

& more
- Add implementation for CYD-E28R28T. This implementation has the SD card working, using the same driver as the CYD-2432S028R.
- Edit .gitignore for some missing things.
- run chmod +x on some build scripts
- Make EspLcdDisplay's reference public for access from drivers (needed for driver St7789i8080)
