The `padLeft` and `padRight` functions were nearly identical and could
benefit from being refactored to share common code.

A new function called `pad` was added that applies padding based on the
sign of the amount of padding needed. A positive value applies padding
to the right side while a negative value applies padding to the left
side.

Issue: #252

The function `maxRuneWidth` was using a flawed approach by only
evaluating strings based on each rune. The `uniseg` package provides a
more accurate method based on grapheme clusters.

This change switches over to the improved implementation which should
achieve better results when determining the maximum width of all
grapheme clusters in a string.
