Outgroup warning

```
10/16/2025 09:58:31 AM [WARNING] Sequences in database of some genus has lower number than MINIMUM_OUTGROUP_COUNT. It may cause error when outgroup selection, or may not select best outgroup. You can either
 1. Lower number of --maxoutgroup
 2. Add more sequences to these groups (validate_input.py:849)
```

Should add information about which genus is lacking numbers
