General issue report

https://github.com/espressif/esp-idf/blob/master/examples/bluetooth/esp_ble_mesh/ble_mesh_sensor_model/sensor_client/main/board.c

Now that ESP32C3 is supported for this example, example will need to be changed for the button to accommodate for the different boards.

For ESP32C3, I have added this to allow the boards to work:

#if(CONFIG_IDF_TARGET_ESP32C3)

#define BUTTON_IO_NUM           9
#define BUTTON_ACTIVE_LEVEL     1

#elif (CONFIG_IDF_TARGET_ESP32)

#define BUTTON_IO_NUM           0
#define BUTTON_ACTIVE_LEVEL     0

#endif
