Support nested array of record about avro

[ThinhLe30]

follow this #138, i've try this:

type RawEvent struct {
			AggregateID string `avro:"aggregateID"`
		}
		type Person1 struct {
			RawEvents []interface{} `avro:"rawEvents"`
		}

but still got the err:

[FAILED] Unexpected error:
      <*fmt.wrapError | 0x14000610e00>: 
      RawEvents: avro: []interface {} is unsupported for avro record
      {
          msg: "RawEvents: avro: []interface {} is unsupported for avro record",
          err: <*errors.errorString | 0x1400014df30>{
              s: "avro: []interface {} is unsupported for avro record",
          },
      }
