Implements a chunked caching scheme for evaluating bijective GroupGeneralMappingByPcgs homomorphisms on PC words. Splits the source pcgs into chunks, caching linear combinations of generator images per exponent pattern, with the bottom elementary abelian layer handled via a matrix over the corresponding prime field. Includes a corresponding ImagesRepresentative method that uses this cached data for a >2.5x speedup, per the included GAPDoc example.
This excludes timing factor, as test overhead kills it.
