Cloud4rpi

* This release adds support for [ESP32](https://en.wikipedia.org/wiki/ESP32)-based boards (like [ESP32-DevKitC](https://www.espressif.com/en/products/hardware/esp32-devkitc/overview)).
 
* The default data sending interval is set to 300 seconds. This frequency is low enough to fit the free data plan if one device works 24/7.

The new **Slider** widget is now supported. You can now [bind a handler for a numeric variable](https://github.com/cloud4rpi/cloud4rpi-esp-arduino/blob/e996a868c10c4a5d70767b2df3aabf5023291280/examples/ESP8266/ESP8266.inoL43) and [process commands](https://github.com/cloud4rpi/cloud4rpi-esp-arduino/blob/e996a868c10c4a5d70767b2df3aabf5023291280/examples/ESP8266/ESP8266.inoL121-L126) sent from the Control Panel.
