-dev versions should probably install examples too.

a widely used practice in Python repos is make style that fixes code structure and imports automatically. It is based on black and isort. Can we have the same?
Here is an example:

style_check:
	black --check .
	isort --check .

style:
	black .
	isort .

@AlexKoff88 that it is used in transformers doesn't automatically mean that this is a widely used practice.

It would, however, be nice to have a similar functionality. I considered adding black before, but the resulting style is pretty much unconfigurable and goes against our current code style at least in terms of used string quoting symbols. Furthermore, black and isort frequently conflict with each other, and also running black/isort does not guarantee that pylint will then pass.

I suggest to keep style out of this PR and review the options for style improvements at a later date.

@AlexKoff88, @vshampor I will try to cover this aspect in another PR.

You are absolutely right. Thanks for the comment.
