* feat: add address.Smart and Decompose for parse CN address

* feat: add Xinjiang directly-administered county-level cities support

- Add '自治区直辖县级市' as a city-level unit (ID: 4043) in A2Data for Xinjiang
- Add 12 directly-administered county-level cities in A3Data (IDs: 4044-4055):
  * 石河子市 (Shihezi, 1976, 8th Division) - ID: 4044
  * 阿拉尔市 (Aral, 2002, 1st Division) - ID: 4045
  * 图木舒克市 (Tumxuk, 2002, 3rd Division) - ID: 4046
  * 五家渠市 (Wujiaqu, 2002, 6th Division) - ID: 4047
  * 北屯市 (Beitun, 2011, 10th Division) - ID: 4048
  * 铁门关市 (Tiemenguan, 2012, 2nd Division) - ID: 4049
  * 双河市 (Shuanghe, 2014, 5th Division) - ID: 4050
  * 可克达拉市 (Kokdala, 2015, 4th Division) - ID: 4051
  * 昆玉市 (Kunyu, 2016, 14th Division) - ID: 4052
  * 胡杨河市 (Huyanghe, 2019, 7th Division) - ID: 4053
  * 新星市 (Xinxing, 2021, 13th Division) - ID: 4054
  * 白杨市 (Baiyang, 2023, 9th Division) - ID: 4055
- All county-level cities are under PID 4043 (自治区直辖县级市)
- Add test case for Xinjiang Shihezi city address parsing
- Now supports parsing addresses like: 新疆石河子市北三路25小区

* docs: formated address data

* fix: parse repeat address error

* feat: update readme file
