Add github action for packaging, update pyproject.toml to use poetry

[amrit110]

PR Type

Packaging

Short Description

• This PR adds a github action workflow that automatically packages the repo and pushes the package to PyPI. The PyPI API token needs to be added to the repo's settings.
• Also updates the pyproject.toml to use poetry for dependency management. When package is built, only the main dependencies are included, not the dev and codestyle dependencies. The poetry.lock file essentially locks all the dependencies so that the entire virtual environment is freezed and is reproducible.

Tests Added

None

Two questions:

1. Should we put a comment in the readme about the Poetry release flow?
2. Is there a way to check that an individual has bumped the version number before publishing?
