*FULLY AUTOMATIC PEAK DETECTION AND INTEGRATION FOR DSC CURVES. SMOOTHS THE CURVE, DETECTS SIGNIFICANT PEAKS, IDENTIFIES INTEGRATION LIMITS, AND COMPUTES AREA UNDER EACH PEAK. ALSO EMITS A DEGREE-OF-CURE CURVE PER PEAK (NORMALIZED CUMULATIVE AREA, 0 TO 1).*
=================================================================================================================================================================================================================================================================

Performs fully automatic peak detection and integration on a DSC (Differential Scanning Calorimetry) curve. Smooths the input curve, detects significant peaks, determines integration limits, and computes the area under each peak. Also emits a degree-of-cure curve per peak as a normalized cumulative area (0–1) from left to right integration limit.

     - Input DSC curve where X is temperature (°C or K) and Y is heat flow (mW or W/g); peaks are detected automatically — provide a single preprocessed DSC scan.
   * - Grouping Percentage
     - grouping_percentage
     - string
     - 5
     - 
     - Percentage of the total X (temperature) range within which nearby peaks are merged into a single result; default is 5% — set to 0 to disable grouping or 100 to collapse all peaks into one group.
