Fix for PIL.Image.DecompressionBombError errors

[nivaca]

I've been having lots of these errors:

PIL.Image.DecompressionBombError: Image size (196310432 pixels) exceeds limit of 178956970 pixels, could be decompression bomb DOS attack.

I fixed it patching pypdfocr_pdf.py by adding the following line:

Image.MAX_IMAGE_PIXELS = None

Everything's working now. However, I don't know if this is the right way of solving this problem. If so, the line could be included in the file upstream.

Suggest to close this as this error prevents excessively large image files from being created (hogging memory and hard disk space)
