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

- converts static arrays to vectors for subpicture related parameters
- improved encoder parameter checking
- mode automatic calculation of subpicture ID length at encoder
- update theoretical limit of maximum number of subpictures

- 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
