Added

cmdline add option "-SD", to create single compressed diffData, for optimize decompress buffer when patch, and support step by step patching when step by step downloading; it's better for IoT! NOTE: old patcher can't work with this new format diffData.
the added create_single_compressed_diff()&patch_single_stream() can be used;
add create_single_compressed_diff_stream(), same as create_single_compressed_diff(), but can control memory requires and run speed by different kMatchBlockSize value;
now, zstd plugin default added in cmdline;

Changed

check_compressed_diff_stream() rename to check_compressed_diff();
patch_single_stream_by() (preview func) rename to patch_single_stream();
