feat: exports init options for external use

[NoodleOfDeath]

This PR simply exports the constructor options for the ChatGPTAPI class so it can be extended/used by other developers! I would rather use this type as a union for my wrapper classes rather than having to manually define it myself! Keep being awesome! Love how active this repo is

i.e.

import { ChatGPTAPI, ChatGPTAPIOptions } from 'chatgpt';

type ChatGPTServiceOptions = ChatGPTAPIOptions & {
  customOption: string;
}

class ChatGPTService {

  api: ChatGPTAPI;
  customOption: string;

  constructor({ 
    apiKey = process.env.OPENAI_API_KEY, 
    customOption = '', 
    ...other 
  }: Partial<ChatGPTServiceOptions> = {}) {
    this.api = new ChatGPTAPI({
        apiKey,
        ...other
     });
    this.customOption = customOption;
  }

}

the reason I was using opts instead of destructuring directly in the constructor is because for some reason in the past typedoc wasn't picking up the correct types to document when I did things this way.

will play w/ typedoc locally after merging this to see if that's still the case :)

@NoodleOfDeath agreed this looks like a great change. always in favor of exporting types instead of trying to pickout types via ConstructorParameters<typeof ChatGPTAPI>[0]
