[FeatureRequest] Save QRCode to SVG, PDF or EPS as well as PNG

[namsor]

Hi ! Thanks for this library. It would be nice to be able to save the QRCode to SVG, PDF or EPS as well as PNG.

For example, adding dependency to
https://github.com/tdewolff/canvas/
the qrcode.go could have

// Canvas returns the QR Code as an image.Image.
func (q *QRCode) Canvas() *canvas.Canvas {
// Based on Image...
}

and this can be saved to appropriate format using,
c := q.Canvas()
c.WriteFile("out.svg", svg.Writer)
c.WriteFile("out.pdf", pdf.Writer)
c.WriteFile("out.eps", eps.Writer)
c.WriteFile("out.png", rasterizer.PNGWriter(3.2))

Attached a draft modification.

Best,
E.
