Description

Most models can be persisted to avoid future retraining. It would be nice to have that same capability for KMeansScorer specifically.

Research direction
Examine existing save() and load() implementations for other models in darts, likely found in models directory. Identify the base class or mixin that provides persistence. Apply the same pattern to KMeansScorer. Review any existing tests for save/load to ensure correctness and compatibility.
