1. SPECK_INT
   Header (9 bytes) + SPECK bitstream
     ^-- num_bitplanes (1 byte) + num_useful_bits (8 bytes)

2. Conditioner
   Booleans (1 byte) + mean (8 bytes) + m_q (8 bytes)
     ^-- Is this a constant field?

3. SPECK_FLT
   Conditioner Stream + SPECK_INT Stream + Outlier_Coder Stream

4. Outlier Coder
   Just the SPECK_INT Stream
