Ixx is correct, Iyy and Izz are slightly off
Fixed Iyy and Izz

Had to change the Iyy and Izz values inside the Cylinder where the
inertiaTensor is calculated. Apparently, the diagram in the slideshow
was for a cylinder rotating about a different axis. Before the fix, my
values were off very slightly. Now they are correct with the answers in
the slide.
