Add text outline/stroke option

What?

Added more text rendering options to add text stroke

page5.drawText('This text is outlined', {
  x: 30,
  y: 80,
  font: helveticaFont,
  color: hotPink,
  strokeColor: blue,
  strokeWidth: 1.5,
  renderMode: TextRenderingMode.FillAndOutline,
});

page5.drawText('Outline only', {
  x: 30,
  y: 10,
  font: helveticaFont,
  strokeColor: hotPink,
  strokeWidth: 1.5,
  renderMode: TextRenderingMode.Outline,
});

Why?

Issues like this: https://github.com/Hopding/pdf-lib/issues/763

Used manually on https://github.com/squareda/pdf-print-marks/blob/main/src/addMetadata.ts#L16 to add outlined text so it's more visible on unknown backgrounds

How?
