Subject: [PATCH] Update filters.py according to pypdf2 (issue #422)

There are some errors in some cases during zlib decompression (eg. I have a PDF with overlay of text, it is the same issue which is documented here https://github.com/mstamy2/PyPDF2/issues/422 ). With this change, the decompression is working without errors.
