This optimizes the conversions between
IntegerandByteString, as we can now rely onIntegerinternals, which lets us use direct copying instead of digit-by-digit extraction and reconstruction.I did not changelog this, as this change is designed to be invisible at the API level. This will require these operations to be re-costed, as this change means we should see an algorithmic improvement (from$\Theta(n^2)$ to $\Theta(n)$ ).
