Error while decoding just encoded data

[Julian Alberts]

While testing my code, I encountered an issue where encoded data could not be decoded.

The following example panics with the message "called Result::unwrap() on an Err value: Error { kind: UnexpectedEof, message: "failed to fill whole buffer" }" at the last unwarp.

 let mut encoded = Vec::new();
 libflate::gzip::Encoder::new(&mut encoded)
    .unwrap()
    .write_all(b"Hello World")
    .unwrap();
assert!(encoded.len() > 0);

let mut decoded = Vec::default();
libflate::gzip::Decoder::new(encoded.as_slice())
    .unwrap()
    .read_to_end(&mut decoded)
    .unwrap();
        
assert_eq!(decoded.as_slice(), b"Hello World")

libflate version 1.3.0
rust version 1.68.0

You need to call Encoder::finish() as follows:

     let mut encoded = Vec::new();
     let mut encoder = libflate::gzip::Encoder::new(&mut encoded).unwrap();
     encoder.write_all(b"Hello World").unwrap();
     encoder.finish().unwrap();
     assert!(encoded.len() > 0);

     let mut decoded = Vec::default();
     libflate::gzip::Decoder::new(encoded.as_slice())
         .unwrap()
         .read_to_end(&mut decoded)
         .unwrap();

     assert_eq!(decoded.as_slice(), b"Hello World")

Thanks, I don't know how I missed this.
