Add LundVariablesTool to JetSubStructureMomentTools for Lund plane jet decoration
This merge request adds the LundVariablesTool implementation to Reconstruction/Jet/JetSubStructureMomentTools.
The following changes were made:
- Added
LundVariablesTool.cxxandLundVariablesTool.h - Modified
CMakeLists.txtto include the new source files
The LundVariablesTool provides a new jet moment decoration that computes and attaches variables derived from the Lund plane to jets. This tool is intended to facilitate studies related to jet substructure using the Lund representation, and integrates with the existing JetSubStructureMomentTools framework.
This MR ensures compatibility with the current upstream main branch and includes all necessary updates to build configuration.
