support generating svg path only

[julia-vetcove]

hi there! great library. using it in react pdf, which requires us to use its own Svg and Path components. it would be useful to have an option to generate just the path of an svg without anything surrounding it. for reference, currently this is my workaround:

const generateQrCodePath = (content: string, size: number) => {
  const htmlStr = new QRCode({ content, join: true, width: size, height: size }).svg({container: 'none'});
  const parsableHtml = new DOMParser().parseFromString(htmlStr, 'text/html');
  return parsableHtml.querySelector('html > body > rect > path')?.getAttribute('d') ?? '';
};

import QRCode from 'qrcode-svg';
...
// in react pdf
return (
  <Svg>
    <Path d={generateQrCodePath(content, size)} fill='black' />
  </Svg>
);
