As described in https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-streaming.html this adds support for reading from a chunked upload encoded request body. The chunked reader modifies the data stream to remove the chunk encoding while validating the chunk signatures in line. This allows the upper layers to get just the object data stream.
