Support reading json string into binary data type.

[zijie0]

Describe the bug

When decoding json string into binary data type, arrow-rs will return JsonError("Binary type is not supported").

To Reproduce

Running the following test could reproduce the error.

#[test]
fn test_json_read_binary_structs() {
    let schema = Schema::new(vec![Field::new("c1", DataType::Binary, true)]);
    let decoder = Decoder::new(Arc::new(schema), 1024, None);
    let batch = decoder
        .next_batch(
            &mut vec![
                Ok(serde_json::json!({
                    "c1": "₁₂₃",
                })),
                Ok(serde_json::json!({
                    "c1": "foo",
                })),
            ]
            .into_iter(),
        )
        .unwrap()
        .unwrap();
    let data = batch.columns().iter().collect::<Vec<_>>();

    let schema = Schema::new(vec![Field::new("c1", DataType::Binary, true)]);
    let binary_values = BinaryArray::from(vec![
        "\u{2081}\u{2082}\u{2083}".as_bytes(),
        "foo".as_bytes(),
    ]);
    let expected_batch =
        RecordBatch::try_new(Arc::new(schema), vec![Arc::new(binary_values)])
            .unwrap();
    let expected_data = expected_batch.columns().iter().collect::<Vec<_>>();

    assert_eq!(data, expected_data);
    assert_eq!(batch.num_columns(), 1);
    assert_eq!(batch.num_rows(), 2);
}

Expected behavior

The above test should pass.
