Added Support For Conversation ID also Tried Fixing Index out of range error

[mukund1606]

Added Optional Parameter from Conversation ID to continue older chats on ChatGPT. Simply Just Copy the https://chat.openai.com/chat/${conversation_id} from url and add as a parameter

Usage: api = ChatGPT(session_token={Session_token}, conversation_id={converastion_id})

Also Tried fixing Index out of range error not sure about the error as never encountered it so can't say for sure if that will work or not

Other than that part, it seems okay to me.
