logdensityof now computes log-density with respect to "root measure" (fixpoint of basemeasure)
Measures should be defined using logdensity_def
basemeasure_type and basemeasure_depth
basemeasure_type is like basemeasure, but on types. More precisely, it makes this square commute:
Using this, we can get basemeasure_depth, a StaticInt giving the number of steps required for basemeasure to reach a fixpoint. And that makes it so we can get a much faster logdensityof using generated functions.
Random.gentype
This already exists, so I replaced our former sampletype with this
