Main function to load the Excel files, check for duplicates, append missing IDs, and save the updated DataFrame back to the Excel file.

## Usage

Run the script with the following command:

```sh
python script.py
```

Example usage within the script:

```python
if __name__ == "__main__":
    main('reinoud.xlsx', 'sisa.xlsx', 'Rolnummer', reinoud_sheet='Actief', sisa_sheet='sheet1')
```

## Logging

The script uses the [`logging`](command:_github.copilot.openSymbolFromReferences?%5B%22%22%2C%5B%7B%22uri%22%3A%7B%22scheme%22%3A%22file%22%2C%22authority%22%3A%22%22%2C%22path%22%3A%22%2Fc%3A%2FUsers%2Fbrech%2FDocuments%2FlocalReps%2Fows-mentoraat%2Fscript.py%22%2C%22query%22%3A%22%22%2C%22fragment%22%3A%22%22%7D%2C%22pos%22%3A%7B%22line%22%3A1%2C%22character%22%3A7%7D%7D%5D%2C%22723f84da-7613-47af-a432-459fba37ba55%22%5D "Go to definition") module to log information and errors. The log level is set to [`INFO`](command:_github.copilot.openSymbolFromReferences?%5B%22%22%2C%5B%7B%22uri%22%3A%7B%22scheme%22%3A%22file%22%2C%22authority%22%3A%22%22%2C%22path%22%3A%22%2Fc%3A%2FUsers%2Fbrech%2FDocuments%2FlocalReps%2Fows-mentoraat%2Fscript.py%22%2C%22query%22%3A%22%22%2C%22fragment%22%3A%22%22%7D%2C%22pos%22%3A%7B%22line%22%3A5%2C%22character%22%3A34%7D%7D%5D%2C%22723f84da-7613-47af-a432-459fba37ba55%22%5D "Go to definition").
