- Prevent negative coefficients on the decode side.
- Prevent illegal coefficients outside the range [-128,127] on the encode side.

- Fix picture header initialization issue when RPR is enabled.

num_extra_slice_header_bits is not present in the spec, and is not used any more in the slice header

  - Add Access Unit detection to support  multi-layer streams containing multiple pictures per AU.

use MAX_NUM_CHANNEL_TYPE instead of MAX_NUM_COMPONENT - 1

Change (0.1, 10000.0 * pow(2.0 , bitdepth_luma_scale)) to the variables encRCGOP::m_minEstLambda and encRCGOP::m_maxEstLambda.

Signalling of CPB timing parameters for sub-layers in DU-based HRD
operations
Remove pt_max_sub_layers_minus1 and use corresponding syntax element in
BP SEI
Make parsing of BP, PT and DUI SEI independent from SPS

Constraint that vps_video_parameter_set_id shall be greater than 0
Added that the bitstream does not contain any VPS when
signalled sps_video_parameter_set_id is equal to zero
(was already in VVC Draft, but not in VTM)

  - Add picture header and related syntax changes.

Generate prefix APS instead of suffix

 Includes decoder side checks that detects if disallowed NAL unit types are used in the bitstream. The implementation is aligned with the spec text in JVET-P2001-v11, apart from the check of prefix and suffix APS NAL units which should be added when prefix and suffix APS is implemented (JVET-P0588/JVET-P0452).
