responseStartRow regex change

[Nyx2022]

now, the responseStartRow regex is ^${HTTP_PROTOCOL_VERSIONS} \\d{3} ${BASIC_LATIN}*$,however, some server may not return standard it only return "HTTP/1.1 200" withou OK as statusText,so iadvise to change regex to ^${HTTP_PROTOCOL_VERSIONS} \\d{3} ?${BASIC_LATIN}*$

in addition ,advised to support http/3 in HTTP_PROTOCOL_VERSIONS

According to the spec HTTP-version SP status-code SP reason-phrase CRLF, the reason-phrase is optional, but the ending space is required:

^HTTP\/\d(?:\.\d)?\s\d{3}\s[^\r\n]+\r\n

HTTP/3 protocol version has been added.

yes , spec is spec,but the real world has some msg is has no space and reason-phrase in the phrase line

[AlexanderMac]

I prefer to follow the spec, otherwise someday the library won't work at all because of many such real world fixes.
