This pull request includes several updates to make the program faster and make the code more concise. The following changes were made:

• Removed unnecessary time.sleep() statements to reduce wait times and make the program faster.
• Implemented explicit waits to further improve program speed.
• Added an exception to check if request limits have been exceeded on Chat GPT.
• Removed all redundant methods and attributes after implementing these changes.
• Added deleteCurrentConversation method to delete conversations after having them.

Hello Basel, first of all thank you for your efforts to make it better, unfortunately you've changed everything in a direction which I would prefer to avoid. However, I liked some of the parts like deleting all conversations and checking if limit exceeded. I am happy to accept them if you can send pull requests in a modular basis.
