Currently we have two pipelines set up: + One pipeline will run pytest to test the code and collect coverage data, this pipeline will run on all branches and PRs. + One pipeline will build the wheel file and publish it to the company's pypl repo, this pipeline will only run on the master branch and develop branch. This RP also made the following changes to make the pipeline working: + Remove `setup.py` and `requirements.txt`, now the project is fully embraced `pyproject.toml`, which according to ChatGPT, is the most modern way of managing a python project. + Move all test files to `tests` folder, so it won't be packed into the final wheel file and affect the coverage rate. + Change version to `X.Y.Z-dev`, before building the wheel file, the pipeline will automatically add a UTC timestamp after it, so it becomes `X.Y.Z-devYYYYMMDDHHmmSS`. This is added due to the limitation of the pypl repo, unlike maven snapshot versions, you can't push the same version twice with our pypl repository.
