tox dependency virtualenv dropped support for creating
Python 3.6 environments in a minor release. [1]
Announce deprecation of Anymail Python 3.6 support.
Until that can take effect, pin an older version of
virtualenv that still works for tox py36 testenv.

Postmark's "test" button in their inbound settings
posts data with attachments that don't match their docs or
actual inbound behavior. Accept that and issue a warning.
Closes#304
If no version-specific tests.test_settings.settings* file
exists for the current Django version, fall back to an
earlier settings file.
- runtests.py find latest settings_N_M earlier than or
matching Django version N.M being tested, rather than
requiring exact match
- remove test_settings files that were just duplicates
of earlier versions
- Add black and isort for Python styling
- Add doc8 for reStructuredText styling
- Add prettier for css/html/js/md/yaml styling
- Run all styling tools from pre-commit hooks
- Adjust flake8 config for compatibility with black
(and current Django style)
- Add some other helpful pre-commit hooks
- Update editorconfig to match Django
(with a few necessary adjustments for Anymail)
- Update `tox -e lint` to run all pre-commit hooks
- Update contributing docs
Work around recent (unannounced) Sendinblue API change
that caused "Invalid headers" API error with non-string
custom header values, by converting basic numeric types
to strings. (Borrowed code from SendGrid backend.)
Fixes#288
Workaround for Django multipart/form-data limitation
where certain attachment filenames cause fields to be dropped
or to end up in request.POST rather than request.FILES.
Handle the MultiValueDictKeyError in inbound webhooks when
this has occurred. Also update docs to recommend avoiding
the problem by using Mailgun and SendGrid's "raw MIME" options.
Also handle reported cases of empty, duplicate keys in Mailgun's
content-id-map.
Fixes#272
pypy-3.8-v7.3.8 accidentally shipped with sqlite v3.7.17,
which is a decade old, and causes the tests to fail with
`django.core.exceptions.ImproperlyConfigured:
SQLite 3.9.0 or later is required`.
Until pypy-3.8-v7.3.9 is available in actions/setup-python,
work around the problem by forcing unqualified "pypy-3.8"
to specific (older) version "pypy-3.8-v7.3.7".
See https://foss.heptapod.net/pypy/pypy/-/issues/3690
and https://github.com/actions/setup-python/issues/339.
