This implementation wraps ``nltk.translate.meteor_score.meteor_score`` while allowing a custom scoring function to be injected (useful for testing).

When omitted the function from NLTK is used. alpha: Precision weight. beta: Penalty exponent. gamma: Fragmentation penalty weight. name: Optional metric name. track: Whether Opik should track the metric automatically. project_name: Optional project name used when tracking.
