Fix ordering in Engine.run_batch

[dstrain115]

• ProcessorSampler incorrectly reconstructs the results from Quantum Engine. It incorrectly assumes that the engine returns results interleaved by sweep point (e.g., S1_P1, S1_P2, S2_P1, S2_P2), when the engine actually returns them grouped by program (e.g., P1_S1, P1_S2, P2_S1, P2_S2).
• This causes the results to be returned incorrectly if jobs_per_batch>1.
