The HypothesisTests module includes a number of statistical tests for comparing against known distributions. Supposing that I have the density for a univariate variable defined as some function, `f(x)`, is there a way to turn this into a UnivariateDistribution that could be passed to, for instance, `HypothesisTests.ExactOneSampleKSTest` along with empirical data?
