Black config added to pyproject.toml

[devanshshukla99]

As of now, the line-length argument is provided to black every time. However, this PR improves the workflow by adding the configuration to the pyproject.toml file.

This PR also adds following extend-ignore arguments to flake8 as suggested by black documentation -- black with other tools

• E203: whitespace before ':' | not PEP-8 compliant
• W503: Line break occurred before a binary operator | not PEP-8 compliant

Not sure if this is worth a changelog entry, but do let me know
