This PR adds a new methodset_pledged_input_size(), which allows users to declare up front how much data will be written to the compressor for a given frame. This combined withCompressionParameter.content_size_flag allows users to ensure that even for streaming compression scenarios the content size is written into the zstd frame header, which is beneficial for reducing decompression memory usage.
