scripts: Dropped --padding from ascii art scripts

No one is realistically ever going to use this.

Ascii art is just too low resolution, trying to pad anything just wastes
terminal space. So we might as well not support --padding and save on
the additional corner cases.

Worst case, in the future we can always find this commit and revert
things.
