Manifest compression defaults to zstd, but the avro format still attempts to load snappy.

in the class `org.apache.avro.file.CodecFactory` we find :
    static {
        addCodec("null", nullCodec());
        addCodec("deflate", deflateCodec(-1));
        addCodec("bzip2", bzip2Codec());
        addCodec("xz", xzCodec(6));
        addCodec("zstandard", zstandardCodec(3, false));
        addCodec("snappy", snappyCodec());
    }
