Implements native sparkline support (line, column, and win/loss) in the Xlsx reader and writer, resolving issue #4941. - New model classes under Worksheet/Sparkline: Sparkline, SparklineGroup, and the SparklineType enum. - Worksheet gains a sparkline group collection with addSparkline(), addSparklineGroup(), getSparklineGroupCollection(), and removeSparklineGroupCollection(), plus deep-clone support. - Reader/Xlsx/Sparklines parses x14:sparklineGroups from the sheet extLst. - Writer/Xlsx/Worksheet emits x14:sparklineGroups; writeExtLst is refactored so conditional-formatting data bars and sparklines share a single extLst. - Adds unit tests, an Xlsx round-trip test, a runnable sample, and docs.
