5992a28e47 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)`

984eb2eff9 lottie: Support the slot reverting feature

5ed068cec3 lottie: Support the slot overriding feature
Internal model and parser modifications have been made
to parse "sid" and retrieve their data into the LottieComposition.
This will enable dynamic changes to the following Lottie objects:

The slot feature will encompass these properties:

- LottieSolidStroke
- LottieSolidFill
- LottieGradientStroke
- LottieGradientFill
- LottieTextDoc"

f64ee28079 Loaders: Introduced a loader cache.
The loader cache is applied to conserve memory.

If the input data is already present in loaders,
the loader cache will promptly return the active loader.

This results in a lot of memory savings for the duplicated resources.

binary diff: -400 bytes

0832a188fe animation/lottie: updated the frame count unit.
replace the frame count unit from the int32_t to float
since animations could smoothly interpolate key-frames.

This notificably improve the animation smoothness in Lottie

Beta API changes:
Result Animation::frame(uint32_t no) -> Result Animation::frame(float no)
uint32_t Animation::curFrame() const -> float Animation::curFrame() const
uint32_t Animation::totalFrame() const -> float Animation::totalFrame() const

df43f91644 loader/lottie: optimize the header task.
To achieve full threading efficiency,
the header should return the necessary properties:
view size, framerate, and duration.

This commit adds duration parsing.

Also don't do the header task in case of single thread
because there wouldn't be parallel effects.
