Save in the association map to the packedCandidates also the mapping from generalTrack to packedCandidate

Better packing of hit information and encoding of that into the pseudoTrack()
Use rounding instead of truncation for fixed precision 16bit encodings
CandPtrSelector: resolve methods at runtime, as for CandViewSelector.
