ScoreLogger manages scoring for a single prediction.
Returned from EvaluationLogger.logPrediction().

## Example

```ts twoslash theme={null}
// @noErrors
const pred = await ev.logPrediction(example, output);
await pred.logScore("accuracy", 0.95);
await pred.logScore("relevance", 0.8);
await pred.finish(); // Finalizes the prediction
```
