**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
I would like to be able to use the arrow_json::ArrayWriter to write Arrow
batches that contain Decimal128 & Decimal256 data.
**Describe the solution you'd like**
Running this code does not produce an error:
```rust
#[test]
fn test_decimal128_encoder() {
let array = Decimal128Array::from_iter_values([1234, 5678, 9012])
.with_precision_and_scale(10, 2)
.unwrap();
let field = Arc::new(Field::new("decimal",
array.data_type().clone(), true));
let schema = Schema::new(vec![field]);
let batch = RecordBatch::try_new(Arc::new(schema),
vec![Arc::new(array)]).unwrap();
let mut buf = Vec::new();
{
let mut writer = LineDelimitedWriter::new(&mut buf);
writer.write_batches(&[&batch]).unwrap();
}
assert_json_eq(
&buf,
r#"{"decimal":12.34}
{"decimal":56.78}
{"decimal":90.12}
"#,
);
}
```
