Dynamically changing speed

[iantearle]

Can't seem to dynamically change the speed timing, note you can globally in settings with animatedSpeed: 1000, but being able to document.documentElement.style.setProperty('--animate-duration', '20ms'); won't work as the variable isn't being used on animate__animated.

I will have a look at it, by the mean time feel free to contribute and open a pull request
