Update truncates string in a way that takes into account ansi color codes.
Existing test/ansi.js did not calculate widths properly because no maxLineWidth given, updated tests truncates line at 21 characters (the largest line width without colors) and compares to ensure color codes do not add to line's calculated width.
Updated test fails with old truncate function, passes with new truncate function, all other tests still pass.
