feat: improve RangeSet performance and add new APIs

Enhanced `RangeSet` operations with sub-linear time complexity for queries (`Contains`, `Overlaps`) and merge-like efficiency for set operations (`Union`, `Intersect`, `Except`). Introduced `LowerBoundComparer` API for external sorting of ranges. Fixed parsing bug for quoted range bounds. Updated documentation with performance improvements and API usage examples.
