PDFDownloadLink: Lazy PDF generation

[ilyabo]

Right now the API is made such that the output PDF is always generated whenever the download link is rendered (Same with the usePDF hook):

<PDFDownloadLink document={<MyDoc />} fileName="my.pdf">
      {({ blob, url, loading, error }) => (
           ...
      )}
</PDFDownloadLink> 

This is quite a waste of resources, because actually rendering is only necessary when the button is clicked. It would be nice if the document prop accepted a function called lazily.

I found this code, but shouldn't it be the default way of rendering supported by the library?

Ah, found that there is an issue already. Sorry.
