Default envs (#120)

* Make use of PlatformIO default_envs option

Makes changing environments/platforms a breeze, no more (un-)commenting:
Simply use the "Switch PlatformIO Project Environment" control in
VSCode.

* Updated README.md to mention ESP32

 Device implementation for Moppy2 for microcontrollers that support the Arduino **framework**.  Currently, the following boards are officially supported:
 - **Arduino [Uno\*]** (via the Arduino IDE or PlatformIO)
 - **ESP8266** (via PlatformIO)
+- **ESP32** (via PlatformIO)
 
 \* Most "Arduino" boards are extremely similar and should work fine, though if you're using PlatformIO you may need to modify `platformio.ini` to match your board-type.
