Review Comment:
```suggestion
for file in files {
println!("file: {file}");
let file = File::open(arrow_test_data(file)).unwrap();
let mut reader = BufReader::new(file);
let header = read_header(&mut reader).unwrap();
let compression = header.compression().unwrap();
println!("compression: {compression:?}");
```
makes debugging of failed tests slightly easier
