This adds --rectify for a parent-aspect-ratio-preserving --squarify variant, reverting squarify to try to match the aspect ratio of a square (1:1). I can see arguments for both of these. On one hand --squarify makes the squarest squares, which according to Mark Bruls et al's paper on the topic is easier visually compare. On the other hand --rectify may be more visually pleasing and fit into parent tiles better. d3 allows for any ratio, but at the moment I'm not seeing a strong reason for the extra parameter.
