Screenshot app & service (#42)
- Added screenshot app & service (PC-only for now)
- Updated docs with screenshots and new device photo
- Add fake statusbar icons for PC/sim build
- added `lv_screenshot` library based on `lv_100ask_screenshot` from https://github.com/100askTeam/lv_lib_100ask
- T-Deck WiFi is now allocated into SPI RAM
- Created `tt_service_find()` to find services by their id

# TODOs
- Update `view_port` to use `ViewPort` as handle externally and `ViewPortData` internally
- Create more unit tests for `tactility-core` and `tactility` (PC-only for now)
- Have a way to deinit LVGL drivers that are created from `HardwareConfig`
- Show a warning screen if firmware encryption or secure boot are off when saving WiFi credentials.
- Show a warning screen when a user plugs in the SD card on a device that only supports mounting at boot.
- Try out Waveshare S3 120MHz mode for PSRAM (see "enabling 120M PSRAM is necessary" in [docs](https://www.waveshare.com/wiki/ESP32-S3-Touch-LCD-4.3#Other_Notes))
- T-Deck has random sdcard SPI crashes due to sharing bus with screen SPI: make it use the LVGL lock for sdcard operations?
- Wi-Fi connect app should show info about connection result
- Check service/app id on registration to see if it is a duplicate id
- Fix screenshot app on ESP32: it currently blocks when allocating memory
# Core Ideas
- Make a HAL? It would mainly be there to support PC development. It's a lot of effort for supporting what's effectively a dev-only feature.
- Support for displays with different DPI. Consider the layer-based system like on Android.
- If present, use LED to show boot status
- 2 wire speaker support
- tt_app_start() and similar functions as proxies for Loader app start/stop/etc.
- tt_app_set_result() for apps that need to return data to other apps (e.g. file selection)
- Make a statusbar service that apps can register icons to. Gui can observe its status changes?
# App Improvement Ideas
- Sort desktop apps by name.
- Light/dark mode selection in Display settings app.
# App Ideas
- File viewer (images, text... binary?)
- GPIO status viewer
- BlueTooth keyboard app
- Chip 8 emulator
- BadUSB
- Discord bot
- IR transceiver app
- Investigate CSI https://stevenmhernandez.github.io/ESP32-CSI-Tool/
