Introduced custom percentile handling for ensemble statistics: - Added "CUSTOM" statistics type and percentile field to RifEclipseSummaryAddress - Refactored RimEnsembleStatisticsCase to store and compute arbitrary percentiles - RimEnsembleStatistics now parses custom percentiles from UI input - RimEnsembleCurveSet and related interfaces updated to handle custom percentile curves and labels - Hashing and statistics calculations now include custom percentiles for cache validity
