Subject: [PATCH] Fix of recognition of ArrayBuffer parameters

If js-sha3 is loaded using 'webpack' loader then the top-most
fuction is not called with global object (`global` in node,
`window` in browsers) and thus `root.ArrayBuffer` is undefined.

This patch introduces usage of `ArrayBuffer` without `root`
prefix similary to how e.g. `Uint8Array` is already used.
