    Country selector

    Selectors 已扩展，现在也包含了 CountrySelector。

    在config flows中使用它可以让 frontend 自动将国家代码翻译成正确的国家名称。

    示例：

    vol.Schema(
    {
        vol.Optional(CONF_COUNTRY): CountrySelector(
            CountrySelectorConfig(
                countries=["DE", "US"],
            )
        ),
    }
)
