This already saves so many digits that I don't feel the need to play games to save an extra byte.

We need to find out if performance tweaking on our end is helpful, or if all the time is already inside the grisu library. By merging the routines, we can avoid the ASCIIString and tuple allocation. There is also some array copying in the `print(digits[1:pt])` types of operations.

It would also be nice to have the `num2str` function back.
