 * @assertion BytesBuilder({bool copy: true})
 * Construct a new empty BytesBuilder.

 * If copy is true, the data is always copied when added to the list. If it copy
 * is false, the data is only copied if needed. That means that if the lists are
 * changed after added to the BytesBuilder, it may effect the output. Default is
 * true.
 * @description Checks that this constructor creates a new empty BytesBuilder.
