Fixes the default schema for the
mapandlisttypes 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 producemaporlisttypes need an arbitrary naming/nullability that we define.Closes #576
