Upgrade dependecy of typing_extensions to ^4.0.0

[thibautd]

Hello,

I would like to know if it's possible to upgrade the dependency to typing_extensions >= 4.0.0.

As of now we cannot introduce some external dependencies like pydantic in our project because of dependency conflicts with django-test-migrations. I don't exactly know if some breaking changes have been introduce in v4, however on the project README we can read the following:

Starting with version 4.0.0, typing_extensions uses Semantic Versioning. The major version is incremented for all backwards-incompatible changes, including dropping support for older Python versions. Therefore, it's safe to depend on typing_extensions like this: typing_extensions >=x.y, <(x+1), where x.y is the first version that includes all features you need.

Please, make a PR! 👍

It doesn't look that simple :-(

  Because no versions of wemake-python-styleguide match >0.15,<0.15.1 || >0.15.1,<0.15.2 || >0.15.2,<0.15.3 || >0.15.3,<0.16
   and wemake-python-styleguide (0.15.0) depends on typing_extensions (>=3.6,<4.0), wemake-python-styleguide (>=0.15,<0.15.1 || >0.15.1,<0.15.2 || >0.15.2,<0.15.3 || >0.15.3,<0.16) requires typing_extensions (>=3.6,<4.0).
  And because wemake-python-styleguide (0.15.1) depends on typing_extensions (>=3.6,<4.0), wemake-python-styleguide (>=0.15,<0.15.2 || >0.15.2,<0.15.3 || >0.15.3,<0.16) requires typing_extensions (>=3.6,<4.0).
  And because wemake-python-styleguide (0.15.2) depends on typing_extensions (>=3.6,<4.0)
   and wemake-python-styleguide (0.15.3) depends on typing_extensions (>=3.6,<4.0), wemake-python-styleguide (>=0.15,<0.16) requires typing_extensions (>=3.6,<4.0).
  So, because django-test-migrations depends on both typing_extensions (^4.0) and wemake-python-styleguide (^0.15), version solving failed.

Ok, I need to release a new version of WPS 😢

[sobolevn]

Now https://github.com/wemake-services/wemake-python-styleguide/releases/tag/0.16.0 with new typing_extensions support is released. Please, report back if anything else is broken! 👍

Done!
