Merge develop into main (#167)

- WiFi Connect app is now hidden by default, but accessible at the bottom of the WiFi Manage app when WiFi is turned on.
- WiFi service now turns on WiFi when calling connect() and WiFi is not on.
- Removed `blocking` option for `service::loader::startApp()`. This feature was unused and complex.
- Various apps: Moved private headers into Private/ folder.
- Various apps: created start() function for easy starting.
- Added documentation to all TactilityC APIs
- Refactored various `enum` into `class enum`
- Refactor M5Stack `initBoot()` (but VBus is still 0V for some reason)
