Returns {@code len} bytes from this buffer, starting at {@code off}.

@param off the starting offset.
@param len the number of bytes to return.

@return the requested data bytes.

@throws IndexOutOfBoundsException if {@code off} or {@code len} is
negative or if {@code off + len} is greater than {@code size()}.
