Decode 1 HT code-block.

Parameters
t1T1 handle
cblkCode-block coding parameters
orient
roishiftRegion of interest shifting value
cblkstyCode-block style
p_managerthe event manager
p_manager_mutexmutex for the event manager
check_ptermwhether PTERM correct termination should be checked

Decode 1 HT code-block.

Parameters
[in,out]t1is codeblock cofficients storage
[in]cblkis codeblock properties
[in]orientis the subband to which the codeblock belongs (not needed)
[in]roishiftis region of interest shift
[in]cblkstyis codeblock style
[in]p_manageris events print manager
[in]p_manager_mutexa mutex to control access to p_manager
[in]check_ptermcheck termination (not used)

State storage One byte per quad; for 1024 columns, or 512 quads, we need 512 bytes. We are using 2 extra bytes one on the left and one on the right for convenience.

The MSB bit in each byte is (\sigma^nw | \sigma^n), and the 7 LSBs contain max(E^nw | E^n)
