Add test requirements, upgrade black

[power-edge]

• adding test requirements per failing tests with missing dependencies
• ignoring virtual environment
• auto-format some files with black .

Description

I saw the # TODO: add test dependencies in the setup.py so I went ahead and captured missing dependencies while running tests.

Motivation and Context

#435

closes #435

I had already fixed the pytablewriter requirement for test_benchmark as of this screenshot

Now after adding test requirements, there is only one failure (and it is not related to missing erquirement)

Note: we are using a maximum length of 127 characters per line

This is the only remaining test failure

Thanks =) I've pushed my edits there: #437

For the full tests, you need to use -r requirements.txt (as in the readme and doc), I remove the readme in the test folder to avoid scattering documentation across too many files.
