Release 1.21.0

[AngusHsu]

Validity changes

• CAN (#635): SocialInsuranceNumber.validate() rejects
  prefixes 0 and 8 under the standard SIN rules, excluding the CESP-specific exception for primary-caregiver SINs
  beginning with 0. checksum() remains an arithmetic-only Luhn check.

Added

• LUX entity TIN (#272): add LUX.EntityTIN, the 11-digit
  national identifier that is used as a TIN-like number for non-natural persons, with the weighted mod 11 check digit
  from the OECD Luxembourg TIN sheet; numbers whose remainder is 1 are rejected because it is never allocated. LUX.TIN
  groups individual (LUX.NationalID) and entity (LUX.EntityTIN). LUX.NationalID is unchanged.
• DEU tax number (#130): add DEU.TaxNumber (alias
  DEU.Steuernummer), the Steuernummer in the 13-digit ELSTER format. It checks the state number, the district rules
  and the state-specific check digit (11er-Verfahren, 2er-Verfahren or the modified 11er-Verfahren of
  Rhineland-Palatinate, with the Berlin-A and Berlin-B weights) from the ELSTER document "Prüfung der Steuer- und
  Steueridentifikationsnummer", and parse() returns the state, tax office, district and distinguishing number. The
  format printed on tax notices is not accepted. DEU.NationalID is unchanged.

Other fixes

• API docs deployment (#644): the apidoc workflow queues its
  deploys in a concurrency group (apidoc-dev for pushes to main, apidoc-<version> for a release) and rebases and
  retries a rejected gh-pages push, so back-to-back pushes to main no longer fail the docs deploy and a push to
  main never cancels a release's docs deploy.
• FRA INSEE (#637): INSEE.parse() (and
  FRA.NationalID.parse()) returns None for a number with a wrong control key, which validate() already rejected.
  Valid numbers parse as before.
• NOR (#637): NationalID.parse() returns None for a number
  with wrong check digits, which validate() already rejected. validate() results and idnumbers.parse_id_info()
  are unchanged.
• Parity corpus (#636): vendor the Node port's parity corpus
  at port commit 782680d, which adds CRI, DOM, ECU, EGY, GTM, RUS and SAU (85 countries, 20,672 vectors), and record
  Python's validity for them, so a validity change in those seven countries now fails tests/parity/test_corpus.py.
  Python's recorded validity for the other 78 countries is unchanged.
