When testing CTA WAVE test vectors the first segment (after init segment) is not requested correctly.

For example with:
php Process_cli.php --cmaf --ctawave --segments http://dash.akamaized.net/WAVE/vectors/cfhd_sets/15_30_60/t1/2022-10-17/stream.mpd

Also worth noting that following the 404 response sent by some servers (e.g. using the basic Python http.server) the conformance tool gets stuck in an infinite loop, constantly re-sending the same incorrect request:
