Django-internationalflavor

==================
* Updates CLDR data to v40
* Support for Django 4.x

==================
* Updates CLDR data to v39
* Support for Django 3.x
* Fixes for Brexit meaning change in VAT numbers

==================
Small release containing updates to translation files. Mostly re-releasing to ensure compatibility
with the new Pip version resolver. Note that the CLDR update to v37 failed because the npm repositories
have not been updated with correct tagging.

==================
* Updates Django support, removing 1.x support
* Updates Python support, removing 2.x support
* Updated CLDR data to v36
* Updated IBAN data, renaming Nordea extensions to experimental countries (based off SWIFT list)
* Updated VAT data, fixing the validation for Dutch VAT numbers
* Added a language field

Due to a packaging error, v0.4.0 as re-uploaded to PyPI without changes to the source itself.

==================
* Fix Django 1.11 bug in the SortedSelect widget. This affects the sorting of optgroups for all versions, they are now
always sorted above other choices.
* Updated CLDR data from v29 to v30.0.3
* ``timezone``: Add Metazone fields, but it is not sorted yet properly :).
* ``vat_number``: Additional cleanup for CH VAT numbers and validation for RU VAT numbers
* ``names``: Add two utilties for joining and splitting (parts of) names. It is best-effort, and not intended to be more
than that.

==================
* Fixes a Django 1.10 bug (I fixed it before, but it never made it into a release...)
* Updated CLDR and IBAN data. Note: UA got an official IBAN, so this means the Nordea alternative got dropped
(SC also got a IBAN, but it was never in the Nordea set).
