Check if something is an ES7/ES2016 async/await function.
i.e. It checks if the function was defined with the async keyword. It does NOT attempt to detect if the function is a traditional asynchronous function, one with a callback.
Compatible with code transformed with Babel 5 and Babel 6.

async keyword.

console.log(isAsyncFn(function () {})) // => false
console.log(isAsyncFn(async function () {})) // => true
