refactored gpu::LUT function:

Browse Source 
* converted it to Algorithm, because implementation uses inner buffers and
  requires preprocessing step
* new implementation splits preprocessing and transform,
  what is more effecient
* old API still can be used for source compatibility (marked as deprecated)
