Fix parsing dependencies in the VUI syntax by moving the
general_progressive_source_flag and general_interlaced_source_flag to
the VUI

- remove picture partitioning section from CTC file (so that they can be combined wit partitioning in any order)
- remove random access parameters from partitioning examples (combines well with AI or LD too)
- add examples for three slices with slice layout inference from subpictures and without
- try to make naming somewhat consistent

- 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
