Merged PR 212: Optimize FindChildrenById from O(n) to O(1)

Optimize FindChildrenById from O(n) to O(1):
- Deprecate FindContainerByIdDFS
- Container: Replace Children to string[]
- Add HashMap to IHistoryState that contains all containers

To access a container by id now cost O(1) without any additional cost

+ Implement CICD for SVGLibs
