Add list functionality to logger

Description

This pull request adds the ability to use multiple instances of notification services simultaneously in the logger. Instead of being limited to a single service per type, users can now configure multiple destinations for each notification service.

Changes Made

📋 Features Added

• Multi-instance support: All notification services (Telegram, Discord, Webhook, Matrix, Pushover, and Gotify) now support multiple instances
• Configuration flexibility: Ability to use either a single object or a list of objects for each service
• Targeted sending: Different events can be sent to different destinations by configuring distinct event lists for each instance

🔧 Technical Modifications

logger.py

• Added Union, List import for typing
• Modified LoggerSettings constructor parameters to accept Union[ServiceType, List[ServiceType], None]
• Implemented _normalize_to_list() method to normalize inputs to lists
• Updated all notification methods to iterate over instance lists

README.md

• Updated documentation to reflect new multi-instance support
• Added "Multiple Notification Support" section explaining new capabilities
• Updated descriptions for all notification services

example.py

• Added concrete examples showing how to use the new features
• Demonstration of configurations with multiple Discord instances and webhooks
• Examples of targeting specific events to different destinations

Usage Examples

Single service configuration

telegram=Telegram(chat_id=123456789, token="...")

Multiple services configuration

telegram=[
    Telegram(chat_id=123456789, token="...", events=[Events.STREAMER_ONLINE]),
    Telegram(chat_id=987654321, token="...", events=[Events.BET_LOSE])
]

Mixed configuration

telegram=Telegram(...),  # Single Telegram
discord=[Discord(...), Discord(...)],  # Multiple Discord

Benefits

• Organization: Separate notifications by importance or team
• Backward compatibility: Existing configurations continue to work without modification

Testing

• ✅ Verified backward compatibility with existing configurations
• ✅ Tested proper functionality with single objects
• ✅ Tested proper functionality with object lists
• ✅ Validated sending to all configured instances

Notes

This feature addresses a community-expressed need to segment and organize notifications according to different criteria. It maintains ease of use while offering increased flexibility for advanced configurations.
