Add Color Property in Lottie KeyPath

[adarsh-grabtaxi]

Is your feature request related to a problem? Please describe.

I am trying to update the lottie animation color for certain keypaths. But to identify the accurate color keypath requires rigourous trail and error as keypaths in android are ambiguous and only show paths for strokes, outlines and fill, etc. I tried to look for an optimized approach not able to find one even couldn't find relevant documentation.

Describe the solution you'd like

Add the color keypath similar to what we have for iOS.
