@brief Configure GPIO pull-up/pull-down resistors

@note ESP32: Only pins that support both input & output have integrated pull-up and pull-down resistors. Input-only GPIOs 34-39 do not.

@param gpio_num GPIO number. If you want to set pull up or down mode for e.g. GPIO16, gpio_num should be GPIO_NUM_16 (16); @param pull GPIO pull up/down mode.

@return - ESP_OK Success - ESP_ERR_INVALID_ARG : Parameter error
