- Support `batchMode` in function properties so, for binders that support batch listeners, a message
payload of `List<byte[]>` can be properly converted.
- In batch mode, handle
`public Function<List<Person>, Person> func()`
`public Function<List<List<Person>>, Person> func()`
`Function<Message<List<Person>>, Person> func()`
- Also use `ParameterizedType` as a conversion hint for `public Function<List<Person>, Person> func()`
when not in batch mode (json: `[{\"name\":\"bob\"},{\"name\":\"jill\"}]`). Previously, just the'
class was used without generic type information.
Move batchMode to ConsumerProperties.
Fix imports
Remove duplicate test from if test for message conversion.
