Decode from a data buffer stream to a CharBuffer stream, either splitting or aggregating incoming data chunks to realign along newlines delimiters and produce a stream of char buffers. This is useful for streaming but is also necessary to ensure that multi-byte characters can be decoded correctly, avoiding split-character issues. The default delimiters used by default are \n and \r\n but that can be customized.
