Broken when parsing PDF with empty object #217

Hi there, I found an error while parsing PDF.

When parsing a PDF file containing an empty object like following,

14 0 obj
<<
>>
endobj

...
/Resources 14 0 R

I got /Resources 0 0 R.
PDF file does not contain 0 0 obj, so the PDF is broken.
I suspect a bug in this method.

Steps to reproduce

Create pdf with empty object

I created pdf file by [Microsoft Print to PDF] in windows 10

Run pdf_data = ::CombinePDF.parse(File.read(pdf_file)).to_pdf
insert something to pdf_data

After this, I opened pdf by Acrobat Reader, and I found an error.
