Avro implementation does not support using defined named types

[VisualBean]

As defined in the specification under Schemas https://avro.apache.org/docs/1.9.0/spec.html#schemas Using already defined names, should be supported. This means that

{
  "type": "record",
  "name": "LongList",
  "aliases": ["LinkedLongs"],                      // old name for this
  "fields" : [
    {"name": "value", "type": "long"},             // each element has a long
    {"name": "next", "type": ["null", "LongList"]} // optional next element
  ]
}

is not supported in the current implementation, as "LongList" is a defined named type, but we dont deserialize it.
