Introduce QuantizerTemplateScaling for SQ #3870

Closed alexanderguzhva closed 1 month ago

alexanderguzhva commented 1 month ago

replace 

template <class Codec, bool uniform, int SIMD>
struct QuantizerTemplate {};

with 

enum class QuantizerTemplateScaling { UNIFORM = 0, NON_UNIFORM = 1 };

template <class Codec, QuantizerTemplateScaling SCALING, int SIMD>
struct QuantizerTemplate {};

This allows adding more Scalar Quantizer scaling types (such as rowwise or rowwise + non-uniform) in the future.
