Arttu Ylä-Outinen a343f6d587 Prepare for delta QPs at CU-level
- Replaces lcu_dqp_enabled with max_qp_delta_depth in encoder_control_t.
- Fixes set_cu_qps so that it can handle quantization groups of
  arbitrary size.
- Fixes computation of QP predictors so that it works for quantization
  groups of arbitrary size.
