* @brief Set country code
* The default value is WIFI_COUNTRY_CN
* @brief configure country info
*
* @param country country type
* @attention 1. The default country is {.cc="CN", .schan=1, .nchan=13, policy=WIFI_COUNTRY_POLICY_AUTO}
* @attention 2. When the country policy is WIFI_COUNTRY_POLICY_AUTO, use the country info of AP to which
* the station is connected. E.g. if the configured country info is {.cc="USA", .schan=1, .nchan=11},
* the country info of the AP to which the station is connected is {.cc="JP", .schan=1, .nchan=14},
* then our country info is {.cc="JP", .schan=1, .nchan=14}. If the station disconnected
* from the AP, the country info back to {.cc="USA", .schan=1, .nchan=11} again.
* @attention 3. When the country policy is WIFI_COUNTRY_POLICY_MANUAL, always use the configured country info.
* @attention 4. When the country info is changed because of configuration or because the station connects to a different
* external AP, the country IE in probe response/beacon of the soft-AP is changed also.
* @attention 5. The country configuration is not stored into flash
* @attention 6. This API doesn't validate the per-country rules, it's up to the user to fill in all fields according to
* local regulations.

* - ESP_OK: succeed
* - ESP_ERR_WIFI_NOT_INIT: WiFi is not initialized by esp_wifi_init
* - ESP_ERR_WIFI_ARG: invalid argument
