Function termimad::wrap::hard_wrap_lines

pub fn hard_wrap_lines(
    src_lines: Vec<FmtLine<'_>>,
    width: usize
) -> Result<Vec<FmtLine<'_>>, InsufficientWidthError>

hard_wrap all normal lines to ensure the text fits the width. Doesn’t touch table rows. Consumes the passed array and return a new one (may contain the original lines, avoiding cloning when possible). Return an error if the width is less than 3.
