[pyup-bot]

This PR updates factory-boy from 2.11.1 to 3.2.0.

Changelog

3.2.0

------------------

*New:*

 - Add support for Django 3.1
 - Add support for Python 3.9

*Removed:*

 - Drop support for Django 1.11. This version `is not maintained anymore <https://www.djangoproject.com/download/supported-versions>`__.
 - Drop support for Python 3.5. This version `is not maintained anymore <https://devguide.python.org/devcycle/end-of-life-branches>`__.

*Deprecated:*

 - :func:`factory.use_strategy`. Use :attr:`factory.FactoryOptions.strategy` instead.
   The purpose of :func:`~factory.use_strategy` duplicates the factory option. Follow :pep:`20`: *There should be
   one-- and preferably only one --obvious way to do it.*

   :func:`~factory.use_strategy()` will be removed in the next major version.

*Bug fix:*

 - :issue:`785` :issue:`786` :issue:`787` :issue:`788` :issue:`790` :issue:`796`: Calls to :class:`factory.Faker`
   and :class:`factory.django.FileField` within a :class:`~factory.Trait` or :class:`~factory.Maybe` no longer lead to
   a ``KeyError`` crash.

3.1.0

------------------

*New:*

 - Allow all types of declarations in :class:`factory.Faker` calls - enables references to other faker-defined attributes.

3.0.1

------------------

 - :py:meth:`get_random_state()` now represents the state of Faker and ``factory_boy`` fuzzy attributes.

*Improvements:*
