min_range = min_T / scale_factor;
      max_range = max_T / scale_factor;
```


e.g. if T = qint8, and initially min_range = -10, and max_range = 9, we would
compare -128/-10.0 = 12.8 to 127/9.0 = 14.11, and set scaling_factor = 12.8
In this case, min_range would remain -10, but max_range would be adjusted to
127 / 12.8 = 9.921875

So we will quantize input values in the range (-10, 9.921875) to (-128, 127).
