Dequantize Int8

Problem

Dequantize a list of int8 codes back to floats: x_i = q_i * scale.

The signature is dequantize_int8(q, scale).

Hint

Dequantization is a single multiply per code, undoing the quantization scale.

case 1

expected: [63.5,-64]

case 3

in: [[2],0.25]

expected: [0.5]

case 4

in: [[0],1]
