Title: Small fixes for density estimation

Querying for the density at a bin centered at zero no longer returns `NaN`. For histograms that have only seen one value, querying the density at that point will return `Infinity`. This, I believe, is the correct result for a histogram whose CDF is essentially a step function.

```clojure
(-> (create)
(insert! 0)
(density 0))
;; Infinity
```
