Run attack from project root

Basic usage:

```bash
python -m attacks.start_attack --attack_name pair --target_model_key llama2_7b --attacker_model_key llama2_7b --judge_model_key llama2_7b --behavior_row 0
```
Using specific behavior ID:

```bash
python -m attacks.start_attack --attack_name pair --target_model_key llama2_7b --attacker_model_key llama2_7b --judge_model_key llama2_7b --behavior_id dimethylmercury_instructions_home
```

Custom behavior config:

```bash
python -m attacks.start_attack --attack_name pair --target_model_key llama2_7b --attacker_model_key llama2_7b --judge_model_key llama2_7b --behavior_config '{"BehaviorID": "test", "Behavior": "Generate harmful content", "ContextString": "Testing context"}'
```

You can start multiple attacks at once by specifying multiple behavior configs:

```bash
python -m attacks.start_attack --behavior_ids behavior1 behavior2 behavior3
# or
python -m attacks.start_attack --behavior_rows 0 1 2
# or
python -m attacks.start_attack --behavior_configs config1.json config2.json
```
