Use `ch` and `em` units

In CSS ch and em units are more focused on the actual characters size, being em the equivalent width to a minuscule m char, and ch the advance of a character, both vertical or horizontal, that means in normal conditions ch is equal to one em in horizontal and two em in vertical. For a monospace font (like a terminal TTY), that means that both ch and em are equal. Taking in account that CSS spec has defined a grid media for monospaced output like TTYs, braille readers and so, it makes totally sense to use both ch and em units as base ones for Ink project… I already did some conversion works in the units repo.

I’m not convinced by the idea yet, I’ll leave the issue open if someone else has a different angle on this topic.
