Updated to Zanshin SDK 1.2.8 to fix the operation that lists scans on a particular scan target.

- Added Windows and Mac OS X to test matrix;
- Rationalized dependencies and updated prettytable and boto3 versions.
- Added new workflow to publish to PyPI and auto-populate the version on both version.py and setup.py based on the Github release tag.
- Fixed lint warnings.
- Implemented a workaround on the typer-cli generation of automated documentation.
- Added timeouts to actions.

Fix a bug on Windows systems when installing package. `setup.py` was not forcing `UTF-8` encoding, leading to installation fail on Windows.
