Implements the rules for interpreting existing data from the logical type
spec for the LIST annotation. This is used to produce the expected schema.
<p>
The AvroArrayConverter will decide whether the repeated type is the array
element type by testing whether the element schema and repeated type are
the same. This ensures that the LIST rules are followed when there is no
schema and that a schema can be provided to override the default behavior.
