- Fixes SDL conversion
- Defer wrapping until types are built
- Supports GraphQL types anywhere that a type can be used, wrapped, etc.
- Split out the wrapping, w/ `finalizeWrapping` helper which adds in the `NonNull` to the list as needed
- Make `nonNull(nonNull(T))` & `nullable(nullable(T))` no-op for simplicity
- Change: `nullable(nonNull(T))` will undo the `nonNull`
- Properly type-check's `subscriptionType` by passing `Event` generic properly
- Adds `declarativeWrappingPlugin` for previous `nullable` / `list` behavior
