Tracks and manages evaluation results, metrics, and logging for model evaluations.

The EvaluationTracker coordinates multiple specialized loggers to track different aspects of model evaluation:

- Details Logger (DetailsLogger): Records per-sample evaluation details and predictions
- Metrics Logger (MetricsLogger): Tracks aggregate evaluation metrics and scores
- Versions Logger (VersionsLogger): Records task and dataset versions
- General Config Logger (GeneralConfigLogger): Stores overall evaluation configuration
- Task Config Logger (TaskConfigLogger): Maintains per-task configuration details

The tracker can save results locally and optionally push them to:
- Hugging Face Hub as datasets
- TensorBoard for visualization
- Trackio or Weights & Biases for experiment tracking

Example:
```python
tracker = EvaluationTracker(
    output_dir="./eval_results",
    push_to_hub=True,
    hub_results_org="my-org",
    save_details=True
)

# Log evaluation results
tracker.metrics_logger.add_metric("accuracy", 0.85)
tracker.details_logger.add_detail(task_name="qa", prediction="Paris")

# Save all results
tracker.save()
```

Aggregates and returns all the logger's experiment information in a dictionary.

This function should be used to gather and display said information at the end of an evaluation run.
