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
