feat: using poetry to manage dependencies

[jjmachan]

using poetry to pin all our dependencies. #45

poetry is used for:

• managing the dependency version
• managing building and publishing to pypi

[jjmachan]

need to decide upon the authentication method we would like to use for the release scripts. These are the available ones and https://python-poetry.org/docs/repositories/#configuring-credentials

[jjmachan]

we can also consider removing the setup.py file completely since poetry covers most of it.
