Execution/Debug/Crash [info]

**Description**
Messages for smooth command-line interface.

- How many domains have been so far processed?
- Which dataset is currently running?
- `;&(){}!¡?¿=.,_$@^*¨%\"<>` characters not permitted by the Domain Naming Convention for Internet User Applications. You can read the formal document from the Internet Engineering Task Force - **[rfc819 - IETF](https://datatracker.ietf.org/doc/html/rfc819)**.

Look at the command-line output code to see where progress messages are printed. Check the domain name validation logic to ensure it rejects the listed special characters according to RFC 819. Run the tool to see current output and identify where to add dataset and domain count messages.
