Bad data type in update_body_from_data

i see elif not self.chunked and isinstance(data, io.BufferedReader):

But using aiobotocore i try

    resp = yield from client.put_object(Bucket=bucket,
                                        Key=key,
                                        Body=open('ANONYMIZE.zip', 'r+b'))

Type of Body is io.BufferedRandom

I replace code to

elif not self.chunked and (isinstance(data, io.BufferedReader) or isinstance(data, io.BufferedRandom)):

And that fix problem.

Got it.
Would you create a PR?
isinstance(data, io.BufferedReader) or isinstance(data, io.BufferedRandom) could be replaced with isinstance(data, (io.BufferedReader, io.BufferedRandom)).
A functional test is required (just sending a file opened with 'r+b' mode should be enough).

Fixed by #1312
