Fixes the default schema for the
map
andlist
types in inference. This isn't a good solution, as there's no guarantee that Arrow doesn't change this behavior in the future. Ideally, we can figure out how to plumb the user map type information through inference. But, it's difficult because functions that producemap
orlist
types need an arbitrary naming/nullability that we define.Closes #576
