deserializing records from htsget stream

[cmdoret]

Dear developers,

When streaming chunks using noodles-htsget, is there a way to lazily parse CRAM records in memory?

In the noodles-htsget example, I've tried to replace:

noodles/noodles-htsget/examples/htsget_download_reads.rs

Lines 32 to 34 in 779500a

	while let Some(chunk) = chunks.try_next().await? {
	stdout.write_all(&chunk).await?;
	}

with things like:

let first_chunk = &chunks
    .try_next()
    .await
    .expect("can't load chunk")
    .unwrap()[..];

let mut reader = Reader::new(first_chunk);
let header = reader
    .read_header()
    .unwrap();

while let Some(chunk) = chunks.try_next().await.expect("can't load chunk") {
  let mut reader = Reader::new(&chunk[..]);
  for result in reader.records(&header) {
    let record = result.expect(&format!("{:?}", chunk));
      println!("{:?}", record);
    }
}

But when trying to instantiate records, I keep getting:

Custom { kind: InvalidData, error: TryFromInt
Error(()) }

Would you have any advice to parsing these records without saving the actual file?
