Get the visual width of the widest line in a string - the number of columns required to display it

Some Unicode characters are fullwidth and use double the normal width. ANSI escape codes are stripped and doesn't affect the width.

Useful to be able to know the maximum width a string will take up in the terminal.

npm install widest-line

import widestLine from 'widest-line';

widestLine('古\n\u001B[1m@\u001B[22m');
//=> 2
