SSE2: speed-up some lossless-encoding functions
...
optimized: CollectColorRedTransforms, CollectColorBlueTransforms, SubtractGreenFromBlueAndRed
overall effect is sub-1% speed-up, though.

SSE2: 53% faster TransformColor[Inverse]
...
Changed the code (again) to process 4 pixels at a time. Loop is more
involved, but overall it's faster.
Removed the SSE4.1 implementation which is now slower than SSE2.
