lottie: follow path stabilization++ 
* lottie: fixes in follow path

Each time the 'updateText' was called, the mask
path (if the follow path existed) was appended
to the previous one, causing it to grow infinitely.
A 'clear' call on the existing path was missing.

The positions on the follow path for distances larger
than 2 x mask path length were not correctly calculated.

* lottie: fix crash on follow path

It could happen that the searched text position
(distance from the start pointt) on the follow path
was exactly equal to the path length. In such a case,
the cmds pointer pointed to the last element, and in
the next iteration, this caused a crash.

b304448ef7 lottie: revert "lottie: more precise culling for inverse mattes" 
This reverts commit 7ef3352efa.

For mattes of type 'InvAlpha' or 'InvLuma', the matted layer
can still be visible regardless of the matte's opacity (unlike
'Alpha' and 'Luma' masks, which cut out the entire layer when
opacity = 0). The previously introduced optimization incorrectly
assumed that with opacity = 255, the image would not be visible.

d3afebfdec lottie: add custom layer effect with expressions support 
effect(name) / effect(index)

effects finds the effect by its name in the Effect Controls panel.
The name can be the default name or a user-defined name.
If multiple effects have the same name,
the effect closest to the top of the Effect Controls panel is used.

example:
- effect("Fast Blur")("Blurriness")

fbe10255d7 lottie/text: added range selector flags 
Duplicated text document properties (fill color, stroke color, and stroke width) to the text range.

If these properties are not defined in the range selector, ThorVG incorrectly overrides them with default values.

The correct behavior is to preserve the original values. The added flags address this issue.

8ec3c841f6 lottie/expressions: add temporalWiggle() support 
usage) temporalWiggle(freq, amp, octaves=1, amp_mult=.5, t=time)

Samples the property at a wiggled time. The freq value is the frequency
in wiggles per second, amp is the amplitude in units of the property
to which it is applied, octaves is the number of octaves of noise
to add together, amp_mult is the amount that amp is multiplied by
for each octave, and t is the base start time. For this function
to be meaningful, the property it samples must be animated,
because the function alters only the time of sampling, not the value.

Note: need to verify this with a practical samples.
