refactor: extract shared feature utilities and sub-program registry from CincinnatiPostProcessor

Browse Source 
Consolidate duplicated static methods (SplitFeatures, ComputeCutDistance,
IsFeatureEtch, feature ordering) from CincinnatiSheetWriter and
CincinnatiPartSubprogramWriter into a shared FeatureUtils class. Move
inline sub-program registry building from Post() into
CincinnatiPartSubprogramWriter.BuildRegistry().
