Incorrect expected style types

[vlinayoDxC]

The following warning message is displayed when using the style={} property in the Lottie component.

Even thought it´s getting the correct styling at the component level, we see the warning because of the configuration used on the propTypes (or that´s what we believe is the reason)

Using this code logic:

So basically it does work but with a bad warning that should be fixed.
We can see the propTypes used at the moment in the file https://github.com/chenqingspring/react-lottie/blob/master/src/index.js
are expecting a string type of value in the styles but they are actually being used as an object.

I have the same issue starting in v1.2.4. I opened #161 to fix it.
