A common mistake is to put a data url (from a canvas for example) as a base64 content. In that case, we got a float value as the computed length of the result and creating an Uint8Array threw an error. This commit hardens the base64 decode: if the computed length is not an integer or if the content looks like a data url, a better error is thrown (instead of "TypeError: invalid arguments").
