[BUG] Library is not pep 517-compliant (adding to a poetry project fails)

[ldorigo]

Describe the bug The project does not follow pep517 (https://peps.python.org/pep-0517/) which means it does not work with modern python packaging tools such as poetry (https://python-poetry.org/)

To Reproduce

Either install poetry and try to poetry add whatsapp-python, or install with pip using pep517 as pip install --use-pep517 whatsapp-python

Expected behavior Package should install correctly

Screenshots
