China provinces are not in the ISO 3166 standard

[mociepka]

At some point in time google replace ISO 3166 province code by full names for China and Russia: https://www.iso.org/obp/ui/#iso:code:3166:CN
https://github.com/mirumee/google-i18n-address/blob/master/i18naddress/data/cn.json

This is problematic and requires mapping like:

CHINA_PROVINCE_MAP = (
    ("AH", "安徽省"),
    ("MO", "澳门"),
    ("BJ", "北京市"),
    ("CQ", "重庆市"),
    ("FJ", "福建省"),
    ("GS", "福建省"),
    ("GD", "福建省"),
    ("GX", "广西壮族自治区"),
    ("GZ", "贵州省"),
    ("HI", "海南省"),
    ("HE", "河北省"),
    ("HA", "河南省"),
    ("HL", "黑龙江省"),
    ("HB", "湖北省"),
    ("HN", "湖南省"),
    ("JL", "吉林省"),
    ("JS", "江苏省"),
    ("JX", "江西省"),
    ("LN", "辽宁省"),
    ("NM", "内蒙古自治区"),
    ("NX", "宁夏回族自治区"),
    ("QH", "青海省"),
    ("SD", "山东省"),
    ("SX", "山西省"),
    ("SN", "陕西省"),
    ("SH", "上海市"),
    ("SC", "四川省"),
    ("TW", "台湾"),
    ("TJ", "天津市"),
    ("XZ", "西藏自治区"),
    ("HK", "香港"),
    ("XJ", "新疆维吾尔自治区"),
    ("YN", "云南省"),
    ("ZJ", "浙江省"),
)

We could add those maps to the lib it self.
