fix(cli): Correctly parse groupby parameter

The `--groupby` command-line argument was not being parsed correctly, causing issues when the column name contained special characters like '/'. The argument was being treated as a sequence of characters instead of a single string.

This change modifies the `import_cmd` function in `src/odoo_data_flow/__main__.py` to split the `groupby` string by commas, allowing for both single-column names with special characters and multiple comma-separated columns to be parsed correctly into a list of strings.

Additionally, new tests have been added to `tests/test_import_threaded.py` to verify the fix and prevent future regressions. The `noxfile.py` was also updated to ensure the `pydoclint` linter runs correctly within the `pre-commit` session.
