Reset this stream to extract from the specified `buffer` containing the specified `numBytes`, set the index of the next byte to be extracted to 0 (i.e., the beginning of the stream), and validate this stream if it is currently invalid. The behavior is undefined unless `0 == numBytes` if `0 == buffer`.
