- add readonlyArray combinator (values are not frozen in production)

Breaking Changes

remove maybe combinator, can be defined in userland as

export function maybe<RT extends t.Any>(type: RT, name?: string): t.UnionType<[RT, typeof t.null], t.TypeOf<RT> | null> {
  return t.union([type, t.null], name)
}
