APIs and tests for retrieving raw/decoded data from image objects
Added FPDFImageObj_GetImageDataDecoded() for retrieving the uncompressed data of an image, and FPDFImageObj_GetImageDataRaw() for retrieving the raw data of an image. * Refactored out DecodeStreamMaybeCopyAndReturnLength(), which is used to decode both attachment data and image data. * Within DecodeStreamMaybeCopyAndReturnLength(), used a different decoder function which takes care of multiple filters if exist. As a result, CPDF_StreamParser::DecodeInlineStream() which was made static previously is now moved back into namespace.
