Pull request overview

Adds extended evaluation and export capabilities to epftoolbox2 by introducing additional built-in evaluators (including a cross-model metric) and a new wide-format CSV exporter, with accompanying report/plumbing and documentation updates.

Changes:

• Extend the evaluator interface to support compute(df, **kwargs) and pass cross-model context (model_dfs) through EvaluationReport.
• Add RMSEEvaluator and rMAEEvaluator (relative MAE vs. a benchmark model) and register them for YAML pipeline serialization.
• Add CsvExporter (wide-format detailed results) and update docs/reference materials accordingly.
