Done.

@liushuangls @sashabaranov I just sumbitted my PR on the (more or less) same topic, I only saw this PR after submbitted mine. However:

@liushuangls just some suggestions:

• do not reimplement Header() for stream, simply embed httpHeader (see my PR).
• ResetRequests and ResetTokens could be both time.Duration without parsing methods.

@sashabaranov let me know how we can handle this duplicate. My personal idea is to go ahead with Liu's PR (with the above suggestions) and use my PR to add headers on streams (with embedded httpHeader) and documentation. The merging order will be first Liu's PR then mine.

@henomis Thanks for your suggestion, the relevant code has been modified

@henomis The reason why the ResetRequests and ResetTokens fields are not directly using time.Duration is that I want to preserve the original values outputted by OpenAI. I believe this approach may help identify some issues. However, if this is unnecessary, I can make modifications accordingly.

Ok @liushuangls I understand. And what about aliasing ResetRequests and ResetTokens as string and attaching ToTime() or Time() method?

type ResetRequests string

func (r *ResetRequest) Time() time.Time {
   // implement here the parser
}

func (r *ResetRequest) String() string{
   // implement here stringer
}

Very good suggestion, code has been modified.

I've just closed my PR, since I think this is a good implementation now.
