I don't think we should handle `DECIMAL` as `double`. `DECIMAL` provides
fixed precision in contrast to `double`. If we internally represent `DECIMAL`
as `double` precision is not guaranteed. I think we need a special data type,
serializers, and also custom math logic to handle `DECIMAL` correctly. Maybe
Calcite offers some of that?
