Refactor serialization code

[ddoktorski]

The current code causes several pyright checks to fail, such as the checks for incompatible field or method overrides. As a temporary solution, these checks have been changed to warnings instead of being treated as errors. Once this is fixed, this condition can be removed from the pyright configuration in the pyproject.toml file.
