@brief GPIO set direction

Configure GPIO direction,such as output_only,input_only,output_and_input

@param gpio_num Configure GPIO pins number, it should be GPIO number. If you want to set direction of e.g. GPIO16, gpio_num should be GPIO_NUM_16 (16); @param mode GPIO direction

@return - ESP_OK Success - ESP_ERR_INVALID_ARG GPIO error
