Provide Extensions to the Prussian Army Death by Horsekick Data

We provide extensions to the classical dataset "Example 4: Death by the kick of a horse in the Prussian Army" first used by Ladislaus von Bortkeiwicz in his treatise on the Poisson distribution "Das Gesetz der kleinen Zahlen", . As well as an extended time series for the horse-kick death data, we also provide, in parallel, deaths by falling from a horse and by drowning.
