fix: print ACL'd images again

The update of the upstream mpdf library in e56751d undid the adjustment
made for the images in 0576bb8.

Since the approach chosen in that commit was declined upstream

This fix will have to be repeated after every update of the upstream
library.

This makes the plugin working on PHP 7.1 again, however I did not look
deeply in how much the API changed and just tried to quickly make the
whole thing work again.

I opted for a composer based install of the library to have the proper
dependencies installed. I also checked in the result to have the plugin
easily install via the extension manager.
