This is tricky: the there are multiple Gumbel distributions too: but both
Wikipedia and Mathworld use the general term "Gumbel Distribution" to refer
to the *minimum* case of the extreme value type I distribution, where as the
distribution currently implemented as "extreme_value_distribution" is the
*maximal* case of the extreme value type I distribution, which is the same
as the ExtremeValueDistribution in Mathematica:

I really wish this wasn't so confusing, but there appears to be no easy
naming choice here.

I wish this had come up in the review, we did think about renaming this at
one point, but never got around to it :-(

If anyone has strong opinions speak up now, as it'll be next to impossible
to make that breaking change after 1.35 has shipped!
