Create an `OverflowMemOutput` using the specified `buffer` of the specified `length` as the initial output buffer. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The behavior is undefined unless `buffer != 0 && length > 0`. Note that this stream buffer does not assume ownership of `buffer`.
