is-webp

I made extended version of this package, which added support of Animated WebP detection. Since WebP Container is based on RIFF, and requires seeking to read animation related bitstream. i thought adopting animation webp detection feature will break your simple code (that's the reason why i love your packages also haha), and it's hard to support "isomorphic package" (e.g. Node Stream, Browser blob...) i decided to make new my own version of instead of breaking your simple code. and i made it! ;) (also there is another related package for Node environment - node-webpinfo - check it out!)

The npm distribution of this package is not properly licensed. It does not contain full license text, which is an issue - see https://github.com/babel/babel/pull/7308#issuecomment-367615152 Effectively, this way the source code distributed on npm is unlicensed and cannot be used by anyone else (or, to be more precise, by anyone who cares about licensing). field in : MIT GitHub repository license file: license npm package contents license: (missing) :warning: To reproduce this issue: Related issue: https://github.com/sindresorhus/ama/issues/537
