Right-to-Left (RTL) support for Hebrew and Arabic

Please add Right-to-Left (RTL) support for languages like Hebrew and Arabic…

Something like:

doc.rtl(true);

doc.text('...', {rtl: true});

Simply reversing the text before it goes to pdfkit seems to work for both Hebrew and Arabic (I’m just eyeballing the text however since I speak neither)

const isHebrew = (text) => {
  return text.search(/[\u0590-\u05FF]/) >= 0;
};

const isArabic = (text) => {
  return text.search(/[\u0600-\u06FF]/) >= 0;
};


const rightToLeftText = (text) => {
  if (isHebrew(text) || isArabic(text)) {
    return text.split(' ').reverse().join(' ');
  } else {
    return text;
  }
};

rightToLeftText('أنا أتحدث اللغة العربية');
rightToLeftText('אני מדברת עברית');

The only correct implementation will be the Unicode bidi algorithm. Anything else, especially reverse(), will be incorrect.
