Main class returns with an error if output directory does not exist

As far as I can see, if the directory in the output path specified in the config file does not exist then there is an error as like:
```
FileNotFoundError: [Errno 2] No such file or directory: '<parent_directory>/anonymizer/output/comma_delimited_file_anonymized_.csv'
```

Adding a control rule that is like create if not exist would be useful to pass this error.
