CI fix: Fix CI failure due to formatting issue

This commit addresses the CI failure in pull request #112 by reformatting the `spice/models.py` file to comply with the required code style. The `model_copy` call has been split into multiple lines to ensure proper formatting. This change should resolve the CI error and allow the pull request to pass the checks.
