Animation options

[andys8]

progressbar.js offers options to configure the animation.

duration: 800,
easing: 'linear',
from: {},
to: {},
step: function() {}

react-progressbar.js offers a toggle initialAnimate, only. It would be great if we would be able to have animationOptions as property. In my case the default value for duration has to be changed.

I could contribute and create a pull request, if the feature is wanted.
