[BUG] CLI Error if --tunnel is used before --dedicatedGnb

**Describe the bug**
If we use --tunnel is used before --dedicatedGnb (or -d) in the CLI, it throws an error.

For example, if we execute this
```
./packetrusher --config config.yml multi-ue -n 2 --tunnel true -d --tunnel-vrf false
```

we get:

```
FATA[0000] You cannot use the --tunnel option, without using the --dedicatedGnb option
```

**To Reproduce**
Steps to reproduce the behavior:
1. Execure `./packetrusher --config config.yml multi-ue -n 2 --tunnel true -d`

**Expected behavior**
The CLI executes normally.

**Architecture (please complete the following information):**
- OS: Debian
- Platform x86_64
- Version 12
- Kernel 6.1.0-17-amd64

Start by running the reported multi-ue command and tracing the CLI option parsing and validation for --tunnel and --dedicatedGnb. Confirm that placing --tunnel before --dedicatedGnb no longer produces the reported error, while invalid combinations still fail as intended.
