Function dynamic_quantize 

pub fn dynamic_quantize(
    input: &Tensor,
    qtype: QuantizationType,
    reduce_range: bool,
) -> Result<(Tensor, f32, i32)>

Dynamic quantization with automatic scale/zero-point calculation

Automatically determines optimal scale and zero point based on input tensor statistics.

Arguments

• input - Input tensor to quantize
• qtype - Target quantization type
• reduce_range - Whether to reduce quantization range for better accuracy

Returns

Tuple of (quantized_tensor, scale, zero_point)
