Let me see.
It looks to me that you can reduce the width of 4th column (of "Byte 1")
to 1.3cm.
If that can not make the table fit in the page width, try reduce the
width of 2nd column (Of "Code").
Another option world be to reduce the font size by using \tiny instead
of \scriptsize in the
.. raw:: latex
directive above the table and reduce widths of every column.
You may need to do a couple of tries and errors.
Good luck!
