VSCode configuration for Python code coverage and debugging

The .vscode/settings.json configuration will produce an HTML code coverage report for the source code folder and save it to the htmlcov folder.

NOTE: running an individual test via the test explorer will result in the code coverage report covering only that test.

The .vscode/launch.json configuration will disable code coverage for debugging sessions with the --no-cov flag, because the two features are incompatible.
