194bd8f01d lottie: Support the Animation Segment(Marker)
A single animation might have a desinated markers with naming: 0 ~ 0.5 (sector A), 0.5 ~ 1.0  (sector B). Selecting one of them using a marker name(sector A) and could play only that part with animation controllers.

usage:
- `animation->segment("sectionA") // Named segment(Marker)`
- `auto cnt = animation->markerCnt()`
- `auto name = animation->markers(index)`
- `animation->segment(0, 0.5) // Segment`
- `animation->segment(&begin, &end)`
