Add method to return PDF as string.

[jonnywilliamson]

Hello again.

One very small feature request to. Would you be able to add a method that returns the PDF created as a string?

At the moment we have download/stream/save which are all useful, but being able to get the pdf as a string would also be very handy and would stop me having to either save the file first before loading it again - or modifying the stream.

Thank you very much sir.

Add the output() method to get a string. Does this work for you?

I'm not sure if i ever replied to this. If I didn't (via email) my apologies.

Thank you for implementing this.
