Setup CI for hulse client

[sachalevy]

Need to set up a basic Github actions file to handle run due to continuous integration for hulse-py. The ci.yaml file should be added to .github/workflows/. Include the following basic steps:

• trigger CI on PR or push to the main branch
• install dependencies (from requirements.txt)
• add linting of python code using black
• run hulse client unit tests
• build and publish docs (see Auto build and publish docs for hulse-py #2 )
• build and release package to github& pypi (see Auto build and release package on github and pypi #3 )
