density_measure_weight

Writing \(N_w\) for the density with respect to weight, the density with
respect to measure \(m\) is \(N_w\) times the factor returned here. With
the allometric weight-length relationship \(w = a l^b\) these factors are
\(1\) for <code>"w"</code>, \(w\) for <code>"log_w"</code>, \(dw/dl = b w / l\) for <code>"l"</code>
and \(l\,dw/dl = b w\) for <code>"log_l"</code>.
