 	Length of each operation can be encoded either directly or via special variable length encoding. From a nibble two bottom bits are preprended to final value, then next nibble is processed, if a new nibble is needed next byte is read from the stream. Process ends if any of two upper bits are set, in that case two upper bits are prepended as well.
