/*
* That usermod implements support of simple hand gestures with VL53L0X sensor: on/off and brightness correction.
* It can be useful for kitchen strips to avoid any touches.
* - on/off - just swipe a hand below your sensor ("shortPressAction" is called and can be customized through WLED macros)
* - brightness correction - keep your hand below sensor for 1 second to switch to "brightness" mode.
* Configure brightness by changing distance to the sensor (see parameters below for customization).
* "macroLongPress" is also called here.
*
* Enabling this mod usermod:
* 1. Attach VL53L0X sensor to i2c pins according to default pins for your board.
* 2. Add "-D USERMOD_VL53L0X_GESTURES" to your build flags at platformio.ini (plaformio_override.ini) for needed environment.
* In my case, for example: build_flags = ${common.build_flags_esp8266} -D RLYPIN=12 -D USERMOD_VL53L0X_GESTURES
* 3. Add "pololu/VL53L0X" dependency to lib_deps like this:
* lib_deps = ${env.lib_deps}
* pololu/VL53L0X @ ^1.3.0
