Added Data.Store.Lens + relevant benchmarks. Most of the time in the DS (Lens) benchmarks is consumed by the preconstruction of the store from the list of element IDs. I am going to cleanup the internals (mainly Data.Store.Internal.Function) in the future and try to incorporate some of the ideas I have for improving the performance.
