===== Trees for quantization unit tree ID storage =====
==== restricted tree ID ====
This tree is used to encode the restricted tree numbers as well as differences between them
  * 0: 1 Bit
  * 1: 2 Bit
  * 2,3: 3 Bit
==== full tree ID ====
This tree is used to encode the Tree ID for a quantization unit, but not for differences.
  * 0: 2 Bit
  * 1-5: 3 Bit
  * 6,7: 4 Bit

==== delta prev tree ID ====
This tree is used to encode differences between the tree ID for one quantization unit and the previous quantization unit of the same channel.
  * 0: 2 Bit
  * 1-3: 3 Bit
  * 4,5: 4 Bit
  * 6,7: 3 Bit
==== delta master tree ID ====
This tree is used to encode the difference between the tree ID used in the slave channel to the one in the master channel for the same quantization unit
  * 0: 1 Bit
  * 1: 3 Bit
  * 2-7: 4 Bit
