The array structure should be faster to populate and query (no properly benchmarked) and reduce memory footprint considerably.
Nevertheless removing PairHMM factor (using likelihoodEngine Random) it only achieves a speed up of 15% in some example WGS dataset
i.e. there are other bigger bottle necks in the system. Bamboo tests also seem to run significantly faster with this change.

Changes:
- ReadLikelihoods added to substitute Map<String,PerSampleReadLikelihoods>
- Operation that involve changes in full sets of ReadLikelihoods have been moved into that class.
- Simplified a bit the code that handles the downsampling of reads based on contamination
Caveats:
- Still we keep Map<String,PerReadAlleleLikelihoodsMap> around to pass to annotators..., didn't feel like change the interface of so many public classes in this pull-request.
