apparatus/cantilever-calib.tex: Move nomenclature out of paragraph

This makes it easier to read the text of the paragraph itself, which
had previously ended a paragraph with a sentence (fixed now).

 To find $\avg{x^2}$, the raw photodiode voltages $V_p(t)$ are
 converted to distances $x(t)$ using the photodiode sensitivity
