Draft: ISF_PunchThroughTools - Adjust PCA to accept splitting by pdgId and eta groupings

Closed Firdaus Soberi requested to merge mumohdso/athena:fix-mpt-pca-23.0 into 23.0

Add the capability for the punch through PCA to accept splitting based on pdgId and eta groups, this is to separate several PCA contributions from protons/neutrons that have distinct energy and eta distribution characteristics than the other punch-through particles.
