Simplified logic of parsing sizes of rice-partitions
> if the partition order is zero, n = frame's blocksize - predictor order
> else if this is not the first partition of the subframe,
> n = (frame's blocksize / (2^partition order))
> else n = (frame's blocksize / (2^partition order)) - predictor order
if the partition order is zero, then partition_number can only be zero
if the partition order is zero, then
(frame's blocksize / (2^partition order))
is (frame's blocksize / 1) == frame's blocksize
