Attempts to decompress the input data using zlib. If the decompression fails due to a zlib error, it falls back to using a decompression object with a larger window size. Please note that the output length is limited to avoid memory issues. If you need to process larger content streams, consider adapting ``pypdf.filters.ZLIB_MAX_OUTPUT_LENGTH``. In case you are only dealing with trusted inputs and/or want to disable these limits, set the value to `0`. Args: data: The input data to be decompressed.
