    MESSAGE RANGE FETCHER
    ---------------------
    
    This script allows you to fetch and display all messages between two specified message IDs in the same channel.
    
    COMMANDS:
    <p>between <start_id> <end_id> - Fetch messages between two message IDs
    
    EXAMPLES:
    <p>between 112233445566778899 998877665544332211 - Fetch all messages between the two given message IDs
    
    NOTES:
    - Both message IDs must be from the same channel.
    - The script fetches messages in chronological order.
    - Will include the messages at both endpoints.
