Telegram Bot with Message Reversal and Story Generation

This is a Telegram bot written in Go that provides two main functionalities:

1. Reverses any incoming message
2. Generates short sci-fi stories using OpenAI's GPT-3.5 API

Features

• Message Reversal: The bot will respond to any message by sending back its reversed version
• Story Generation: Use the /story command to receive a randomly generated sci-fi story (max 400 characters)
• Environment Variables: Secure configuration using .env file
• Docker Support: Easy deployment using Docker and Docker Compose
