pdftopdf (in PPV) is not available on OS X catalina

Following https://github.com/Evidlo/remarkable_printer/issues/6 I used the PPV and lpadmin to set up on a mac, but I got an error in the CUPS interface that pdftopdf is not present.

This patch seemed to solve this for me, ensuring that raw PDF is sent to the reMarkable jetdirect socket:

On reflection, looks like this is a dupe of https://github.com/Evidlo/remarkable_printer/issues/22

What if you replace pdftopdf with -?

Yep, that does seem to work (I missed that the line above it already did this!). I've sent a pull request.
