Improve type-checker mypy configuration

[daniel-zullo-frequenz]

What's needed?

The type checker mypy is configured to check specific packages within a repository. In practice, there are repositories that contain more than one package. This setup is not ideal because typically only one package is configured to be type-checked by mypy. As a result, parts of the codebase may not be checked, leading to potential type-related issues going unnoticed.

To ensure type-checking, all relevant packages should be included in the mypy configuration. This would help in maintaining type consistency and catching errors across the entire codebase.

Proposed solution

Replace the setting of packages and use files and mypy_path instead as follows:

Current configuration:

packages = ["your_package_name"]  # Use the actual package name here

to be replaced by:

files = ["src", "tests"]
mypy_path = "src" 

This will ensure the codebase is fully type-checked (at least for any file within src and tests) without the need for the user to set explicitly the packages.
