Coder stages

Stage	Description
HuffmanStage	GPU Huffman entropy coding (PHF coarse-grained)
ANSStage	GPU rANS entropy coding (dietGPU, byte-level)
GPULZStage	GPU LZSS (LZ77 + flag-bitmap) lossless compression (GPULZ)
RLEStage	Run-length encoding
RZEStage	Recursive zero-byte elimination
RREStage	Repetition-reduction encoding (LC framework lossless component)
RAREStage	Repetition-adaptive reduction encoding (LC framework, auto-k generalization of RRE)
RAZEStage	Zero-adaptive reduction encoding (LC framework, auto-k generalization of RZE)
CLOGStage	Compressed-Logarithm adaptive bit-width coding (LC framework lossless component)
HCLOGStage	Compressed-Logarithm coding with per-subchunk TCMS fallback (LC framework lossless component)
BitpackStage	Dense bit-packing of fixed-width integers
AdaptiveBitpackStage	Per-block adaptive fixed-rate bit-plane coding (cuSZp plain mode)
