New `scipy.stats.Logistic` distribution

In scipy/scipy#23259 I’ve added a new logistic distribution, using the new distribution infrastructure (docs), as scipy.stats.Logistic. Like scipy.stats.Normal, its location and scale are “standard” (but can of course be scaled or shifted), and it has a wide range of applications (e.g. logistic regression). So I figured it would be nice to have it as well.
I was asked to open a thread here, so here I am :slight_smile:.

Looks nice! By the way, do you foresee a place for a method to fit the (location and scale) parameters to a sample of i.i.d. observations?
