DAC on the KC868-a6

[tanoshimi]

Yes. The Kincony labelled diagrams show the pins laid out like this, and the demo code declares `DAC1 = 26, DAC2 = 25`.

But, the ESP32 CPU schematic (as shown in my previous post), and also the pin definitions the Arduino ESP32 libary have them the other way around: 
```DAC1 = 25, DAC2 = 26.```

See here for where they are defined: https://github.com/espressif/arduino-esp...uino.h#L49
