* Revert "move back!"
This reverts commit d3694365c634acc5db62ac59771c496cb971a727.
* fix some of the things
* Addressing feedback? hmm
* Fixes
Bug 1 — Reconnect loop / Reconnect not working fixed

* Addressing things and device fixes
* Missed one!
* stuff

Auto starts the web server in AP mode with generated SSID and Password.
For small devices.... or any i guess.
Hidden by default.
May need adjustments to suit even smaller screens than the waveshare GEEK.
And a few symbols for good measure. :)
* **Refactor**

* Device trees and drivers now use GPIO phandle-style pin specifications across all boards and all drivers.

* Espnow chat fix
Fixes chat app not appearing and coexistence with wifi STA mode.
Wifi OFF and obviously not connected, espnow starts.
Wifi ON and connected, espnow starts.
Wifi ON and NOT connected, espnow starts.
* Fix P4 build
- `TT_LOG_*` macros are replaced by `Logger` via `#include<Tactility/Logger.h>`
- Changed default timezone to Europe/Amsterdam
- Fix for logic bug in unPhone hardware
- Fix for init/deinit in DRV2605 driver
- Other fixes
- Removed optimization that broke unPhone (disabled the moving of heap-related functions to flash)
Lots of things "ported" over from the "enhanced" fork. With some adjustments here and there.
KeyboardBacklight driver (for T-Deck only currently)
Trackball driver (for T-Deck only currently)
Keyboard backlight sleep/wake (for T-Deck only currently...also requires keyboard firmware update)
Display sleep/wake
Files - create file/folder
Keyboard settings (for T-Deck only currently)
Time & Date settings tweaks
Locale settings tweaks
Systeminfo additions
Espnow wifi coexist
initI2cDevices - moved to T-deck init.cpp / initBoot
KeyboardInitService - removed, moved to T-deck init.cpp / initBoot
Adjusted TIMER_UPDATE_INTERVAL to 2 seconds.
Added lock to ActionCreateFolder
Maybe missed some things in the list.
Display wake could do with some kind of block on wake first touch to prevent UI elements being hit when waking device with touch. Same with encoder/trackball/keyboard press i guess.
The original code was written by @cscott0108 at https://github.com/cscott0108/tactility-enhanced-t-deck
- Implement generic ESP32 devices
- Updated GitHub Actions to first build the SDKs. These are now based on the generic device implementations and the build act as a filter before compiling the dozens of other devices. It should save on resources when boards fail to compile.
- Adapted code to C6 and P4 differences, heavily borrowed from from https://github.com/ByteWelder/Tactility/pull/394 written by @marciogranzotto, with some changes of my own
- Updated `device.py` to make the `[display]` section optional
- WiFi code cleanup
- When WifiConnect opens and SSID is filled in, automatically focus on the password field
- When no touch screen is present, toolbar close buttons should be automatically selected
- When `device.py` selects a device, print it on screen
## Improvements
- Created new base driver classes: `EspLcdDisplayV2' and `EspLcdSpiDisplay`
- Updated `St7789Display` to implement `EspLcdSpiDisplay`
- Updated all boards with ST7789 display
## Fixes
- Ensure that `tmp/` is created on startup (for all writeable filesystems)
- Fix for `lv_list` padding on small screen devices
- Fix for `PreferencesEsp` not processing result when writing string to NVS
## Other
- Remove unused build scripts
- Added `AppHub` app
- Added `AppHubDetails` app
- Added `cJSON` dependency
- Renamed `AppSim` module to `FirmwareSim`
- Added extra `tt::app::alertdialg::start()`
- Renamed `addApp()`, `removeApp()`, `findAppById()` and `getApps()` to `addAppManifest()`, `removeAppManifest()`, `findAppManifestById()` and `getAppManifests()`
- Added `tt::lvgl::toolbar_clear_actions()`
- Added `tt::network::EspHttpClient` as a thread-safe wrapper around `esp_http_client`
- Added `tt::network::http::download()` to download files
- Added `tt::network::ntp::isSynced()`
- When time is synced, the timestamp is stored in NVS flash. On boot, it is restored. This helps SSL connections when doing a quick reset: when WiFi reconnects, the user doesn't have to wait for NTP sync before SSL works.
- Added `tt::json::Reader` as a `cJSON` wrapper
- Added `int64_t` support for `Preferences`
- Added `int64_t` support for `Bundle`
- Added dependencies: `cJSON`, `esp-tls`

- Added `tt::string::join()` that works with `std::vector<const char*>`
- Fixed `tt::file::getLastPathSegment()` for the scenario when a path was passed with only a single segment
- Set `CONFIG_ESP_MAIN_TASK_STACK_SIZE=5120` (from about 3k) for all boards
- Set `CONFIG_MBEDTLS_SSL_PROTO_TLS1_3=y` for all boards
New boards:
- LilyGO T-Dongle S3
- M5Stack StickC Plus
