Inconsistent output between pretty print and CSV writer for Arrow

[alamb]

Describe the bug
The formatting of floats as printed by pretty_print_batches and the CSV Writer is inconsistent

To Reproduce

fn main() {

    let arr = Float64Array::from(vec![Some(1.0), None, Some(2.0)]);
    let batch = RecordBatch::try_from_iter(vec![
        ("col", Arc::new(arr) as _)
    ]).unwrap();


    println!("Display");
    println!("{}", pretty_format_batches(&[batch.clone()]).unwrap());

    println!("CSV");
    let mut writer = Writer::new(std::io::stdout());
    writer.write(&batch).unwrap();

}

Produces the output:

Display
+-----+
| col |
+-----+
| 1   |
|     |
| 2   |
+-----+
CSV
col
1.0
""
2.0

Note how pretty print shows 1 and csv shows 1.0

Expected behavior
I expect the displays to be the same (likely by making the csv writer consistent with the pretty printer)

Additional context
See other usecase on on apache/datafusion#4876

I think #3483 from @JayjeetAtGithub covers one potential implementation mechanism
