      Description

      I'm not sure how to expose this. The easiest, implementation-wise, would be to allow passing a Schema (for example inside the ConvertOptions).

      Another possibility is to allow specifying the default types for type inference. For example type inference currently infers integers as int64, but the user might prefer int32.

      Thoughts?
