While enforcing the maximum chunkSize on a Server-Side (node.js) I realized that the last chunk is often bigger than the configured chunkSize. The source code states this is how it is supposed to be at https://github.com/23/resumable.js/blob/master/resumable.js#L259

Why are we doing this? And if there is a good reason for it, shouldn't we mention the behavior in the documentation?
