Create a delivery object based on the specified tag. This form
of the method is intended to allow the tag to be formed from a
subsequence of the byte array passed in. This might allow more
optimisation options in future but at present is not
implemented.
@param tag a tag for the delivery
@param offset (currently ignored and must be 0)
@param length (currently ignored and must be the length of the <code>tag</code> array
