Allow zero length streams when parsing.chromium/3130
It's possible to create a stream of length 0 in a PDF document.
Currently the code will early exit and return a nullptr. This causes
issues when you want to print the given PDF as the FPDF_ImportPages code
ends up only generating up to the zero length object.
This CL allows creating streams with length 0 and updates the PDF saving
code to output a blank stream.
