Expand description
Construct an iterator over each new line (\n or \r\n) and returns the categorised slices within those.
CategorisedSlices that include a new line are split with the same style.
Example
let s = format!("{}{}\nhow are you\r\ntoday", "hello, ".green(), "world".red());
let cat = categorise_text(&s);
let mut iter = line_iter(&cat);
let first = iter.next().unwrap();
assert_eq!(first[0].text, "hello, ");
assert_eq!(first[0].fg_colour, Color::Green);
assert_eq!(first[1].text, "world");
assert_eq!(first[1].fg_colour, Color::Red);
assert_eq!(&construct_text_no_codes(&iter.next().unwrap()), "how are you");
assert_eq!(&construct_text_no_codes(&iter.next().unwrap()), "today");
assert_eq!(iter.next(), None);
