slide_median? #203

Thanks for this excellent package! Using slide_mean is very fast, slide_dbl(x, median) is a lot slower. Would it be possible to implement a slide_median function?

A rolling median is computationally much different from a rolling mean and doesn't fit particularly well with the fast implementation that backs slide_mean/all/any/etc. I looked into it awhile back when I was implementing those, and while it is possible, it would be a lot of work and I doubt I'll have time for that in the short to medium term
