DNS name

**Describe the solution you'd like**
I want to know DNS name as well


expecting something like:

```bash
+-----------------+----------------+-----------+
| DNS Server | DNS Name | Status |
+-----------------+----------------+-----------+
| 1.1.1.1 | one.one.one.one | Forbidden |
| 8.8.8.8 | dns.google | Forbidden |
| 185.51.200.2 | iranian-dns.com | OK |
+-----------------+----------------+-----------+

```

Benefits

- The DNS name column provides more context about the DNS server.
- Enhances the readability and understanding of the server details.

The issue is about adding a DNS name column to the CLI output. Look for the code that fetches and displays DNS server information, likely in a command like 'bestDNS' or 'check'. Find where the table is formatted and add a new column. You'll need to perform a reverse DNS lookup (PTR record) for each IP address. Check existing tests for the output format to ensure the new column integrates correctly.
