HI Cloudflare Team.

This issue related with #2200
Description
When we don't use --dump-response overall time delays because of copying & converting types into String.
So I this issue fixes error by writing stdout even if we do not use --dump-response.
Error Reproduce
Make dump file
dd if=/dev/zero of=/tmp/1GB.bin bs=1M count=1024Open the server
cargo run --bin quiche-server -- \
--listen 127.0.0.1:4433 \
--cert apps/src/bin/cert.crt \
--key apps/src/bin/cert.key \
--root /tmpRequest with --dump-response
time cargo run --bin quiche-client -- \

--dump-responses /tmpRequest without --dump-response
time cargo run --bin quiche-client -- \

We can check it takes more time when not using --dump-response
