Resets this stream, so that all currently accumulated output in the output stream is
discarded. The output stream can be used again, reusing the already allocated buffer space.
Creates a byte string with the size and contents of this output stream. This does not create
a new copy of the underlying bytes. If the stream size grows dynamically, the runtime is
O(log n) in respect to the number of bytes written to theOutput. If the stream size
stays within the initial capacity, the runtime is O(1).
