Lesson20 - extend hardware digital output and input channels in home assistant

[admin]

1. extend output and input ports by hardware device

a. KC868-A series board  (integrate to home assistant by ESPHome)
b. KC868-HxB series board (integrate to home assistant by MQTT)

2. config ESPHome for KC868-A16
