Data chunks with fixed length except for trailing chunk, matching overall stream length
I have problem with decoding data chunks by ksy file. My data chunks have fix size of 16 bytes, but last data chunk must have to len matched to the rest of stream. It's mean last data chunk must have size of (total_bytes_stream by mod 16) bytes. 
* Data_chunks (46b) :
** data_chunk1 - len 16 bytes  
** data_chunk2 - len 16 bytes 
** data_chunk3 - len 14 bytes

How to do it?
