Unable to parse when the returned packet is not in normal http format

[No-Github]

httpx version:

v1.2.6

Current Behavior:

[DBG] Failed 'http://*.*.*.*:8080': GET http://*.*.*.*:8080 giving up after 1 attempts: Get "http://*.*.*.*:8080": net/http: HTTP/1.x transport connection broken: malformed MIME header: missing colon: "user\""

[DBG] Failed 'http://*.*.*.*:8080': invalid header line: "user\"\r\n"

Expected Behavior:

The target is accessible and should have normal result output

Steps To Reproduce:

1. fofa query: "wf2411" && port="8080"
2. echo "*.*.*.*:8080" | httpx -debug -unsafe

Anything else:

@No-Github Thanks for opening this issue. Unfortunately the standard library enforces strong validation on http protocol. Probably this will be indirectly fixed with projectdiscovery/rawhttp#112

Although it is possible in some hacky way to override the internal net/textproto/reader.goreadMIMEHeader via linking after testing, it seems pretty much unreliable as the rest of the response fail to be parsed, and numerous runtime errors are introduced. Closing as not planned for the time being, it will be indirectly fixed with projectdiscovery/rawhttp#112 fallback mechanism
