Add "Events Advanced" page and route

[jessedegans]

This pull request introduces advanced examples of Solidity events. It builds on the basics covered in the existing Events documentation with two examples: EventDrivenArchitecture and EventSubscription. These examples demonstrate event-driven architecture and real-time event subscription mechanisms.

Changes Introduced

• Added EventDrivenArchitecture Contract:

  • Demonstrates the use of events to coordinate and trigger different stages of a process (e.g., initiating and confirming transfers).
  • Includes two events: TransferInitiated and TransferConfirmed.
  • Implements functions to initiate and confirm transfers.

• Added EventSubscription Contract:

  • Showcases how to implement event subscriptions for real-time updates.
  • Includes the subscribe and unsubscribe functions to manage subscribers.
  • Emits LogTransfer event and notifies subscribers via the handleTransferEvent function.

Additional Information

• Version: 0.8.14
• Keywords: [events, advanced, event-driven, monitoring, filtering, security]
