- new pattern: create a class to collect all parameters  related to this SEI
- existing code can be refactored to use the same pattern for grouping to avoid endless assignments

Note: fixes executable flags for some unrelated config files

New configuration file can be used in conjunction with existing AI, RA and LD
configuration files. It is to be used with more common 1920x1080 picture size.

Modifications to VPS syntax (signal PTL for single layer OLSs)
PTL part only (HRD part to be implemented by Sharp)

- don't access SPS/PPS references which are not set
- also fixes config files

JVET-O1143: motion and in-loop filter low-level operations adaptation when subpic boundaries are treated as pic boundaries

Slice-level switch between TS residual coding and regular residual coding for lossless coding as in JVET-Q0089.
One SPS flag that controls both luma and chroma BDPCM simultaneously as under JVET-Q0089 (meeting notes) - removed chroma BDPCM flag.
Modified the .cfg files to reflect high-level chroma BDPCM changes.
Fix: Disabled CCALF in lossless.cfg (necessary) CCALF cannot be used if ALF is disabled (disabled in lossless.cfg)

Sets CTC screen content config to use chroma BDPCM as in JVET-Q0785
Aligns Intra Prediction mode with BDPCM mode for chroma as in JVET-Q0110
Adds separate chroma contexts for BDPCM as in JVET-Q0110
Aligns signaling order for chroma BDPCM to match with Spec as in JVET-Q0351 and JVET-Q0785
