What this PR does:

This PR introduces a significant update to the SDK, focusing on improved provider management and connection handling.

The core changes include:

SDK Implementation:

• Developed a robust SDK class to manage wallet interactions, including connection and disconnection operations.
• Added methods for common wallet functions, such as getAccountInfo and sendTransaction.

Provider Injection:

• Implemented provider injection into the SDK class, allowing for flexibility in using different wallet providers
  (e.g., AdenaWalletProvider).
• Providers are now managed through a ConnectionManager class that handles connection state and events.

Connection Management:

• Added a ConnectionManager class to manage connection state and emit events for connection changes
  (connected and disconnected).
• Provided methods to register and unregister event listeners for connection state changes.
