What changed

Follow-up to #59 (merged). Adds two orange triangles to
pls/pls-model-inversion-null-space.png marking the two null-space moves from
the pid-book text: a down triangle at the -1 step and an up triangle at the
+1 step along the taste-20.9 null-space line. Both points predict the same
taste as the direct-inversion solution, illustrating that moving along the null
space leaves the prediction unchanged. The generator
pls/pls-model-inversion-null-space.py is updated to match.

Adds a down triangle at the -1 step and an up triangle at the +1 step along
the taste-20.9 null-space line (the two moves shown in the book text). Both
predict the same taste as the direct-inversion solution.
