Package bundle size increases around 98.5% due to a gif file used in readme

If you go to npm page is this library, it says unpacked size is 3.4 mb. If you don't look into the source code directly, you'll think the library's bundle size is too big. But most it is coming from as gif file used in readme file commited in the bundle file.

Although it doesn't affect production build of the apps which uses this library, it is kind of misleading and might affect potential user's decision to use this library.
