Updated code to be universal. So it can be executed in node environment.

This PR enables the image component to be executed on server side for SSR. Otherwise it throws following error.

ReferenceError: window is not defined
at new r (<path>/node_modules/react-lazy-load-image-component/build/index.js:1:7434)
...

Additionally we can use it with visibleByDefault option visibleByDefault={typeof window === "undefined"} to output image src tags from server rendered content.

Thanks for this issue. It solved my problem. Had to do the following to make my component work with server side rendering:

<LazyLoadImage className={styles.footerImage}
               effect="opacity"
               visibleByDefault={typeof window === "undefined"}
               src={require("../../images/super-cool-image.png")}
               alt="Super cool alt tag"/>
