Title: Support for front and back Buffers

Creating a pdf in memory for the front and back of a postcard and then writing it to disk only to read it again is less than ideal.

This PR allows for the passing of a generated pdf (via a buffer) directly to the postcard create function. Note, if a buffer is encountered when populating the form for the request, it is assumed that it is a pdf doc and a filename is generated.
