Support xLabel, yLabel options for density

Seems to be supported for viz.hist but not viz.density

I'll add this to my todo list, but it's not high priority.

In general, if you pass in a distribution rather than an array of samples, you can set the labels by changing the keys of the objects:

viz.density(
  MH(function() { return {foo: uniform({a: 0, b: 1}) } }, 60)
)

Btw, in the big overhaul I'm planning, you won't even be able to pass in array of samples - it'll have to be either a data frame or a distribution. This will hopefully solve a lot of the awkwardness around axis label tweaks, tick label rotations, type hints, etc.

That makes sense. I've advised the probmods students accordingly
