描述

The standard zstd tool has a --stream-size option so the file size can be set for streamed compression. However, pzstd doesn't support this option, so any file compressed with pzstd has to be decompressed with a stream (so, eg, the PyPi zstd module can't be used).

研究方向
Start by examining how the standard zstd tool implements the stream size option, likely in programs/zstdcli.c. Then locate the equivalent pzstd source files (e.g., programs/pzstd.c or similar). Understand how pzstd handles compression options and add a new option to set the stream size. Ensure compatibility with the streaming API. Consider any related code in the repository that handles stream sizes for decompression.
