uploadFiles and downloadFile have different error handling logic.

Hi,

I noticed that in uploadFiles the http status code that is greater than or equal to 400 is handled internally and is thrown as an error. See code

But downloadFile doesn't do the same. See code.

Also, the Error thrown by uploadFiles has an untyped field result. It's useful, but since it's not typed and is optional, we have to type it by ourselves.

I think it's better that they are consistent and there is a dedicated type of Error for http error responses.

Yes, I agree. uploadFiles() got recently updated, because of #48 / PR #49, but I had not arrived to update downloadFile() in the similar way. Please, submit a PR if you need it and have capacity to do it.
