Creates a tag controller from the tag of the specified buffer or stream.
The function will read the whole tag, but probably not the whole stream,
so performance-wise it's favorable to send the stream and not the whole file's buffer if possible.
Additionally, if there is no tag there or you call the function without arguments,
the function returns an empty tag.
