Create directories and pyproject.toml

[lisphilar]

This is the initial issue and to set-up development environment.

1. Create the following directories and pyproject.toml with poetry.

$ tree
.
├── LICENSE
├── README.md
├── dim
│   ├── __init__.py
│   └── __version__.py
├── poetry.lock
├── pyproject.toml
└── tests
    ├── __init__.py
    └── test_metadata.py

2. As discussed in Slack, users will install this library with poetry add dim-python or pip install dim-python after release.

3. Users will use the library with import dim; dim.__version__.

4. Documentation will be on README.md at this time. We may use Sphinx later.

5. The following dependencies will be used for tests, if acceptable.

• pytest = "^7.1.3"
• pytest-cov = "^4.0.0"
• flake8 = "^5.0.4"
• autopep8 = "^1.7.0"
• pyproject-flake8 = "^5.0.4.post1"

.gitignore for Python will be also created.
Template: https://github.com/github/gitignore/blob/main/Python.gitignore

Additionally, I added GitHub Actions workflow (.github/workflow/test.yml) to run tests for each push on main and pull requests.

Please review my initial pull request for this issue.

Reopened to updates:

• Rename ".github/workflow/" to ".github/workflows" (fix naming error to activate GitHub workflows)
• Include Lint workflow with flake8 /autopep8, which were added as dev dev dependencies but not used test.yml
• Add ".vscode/" (files for editors) to .gitignore
