feat: add aa errors

[joepegler]

What

Integrate the AA Errors repository to provide better error handling and user feedback in our SDK.

Why

Integrating the AA Errors repository will significantly improve our SDK's error handling capabilities:

• Provide immediate, actionable advice to users when issues arise
• Clarify cryptic AA errors in a cause-and-effect format
• Leverage over two years of troubleshooting knowledge from the AA stack
• Improve developer experience by offering solutions to common debugging challenges
• Contribute to the AA community by sharing our error-handling knowledge as a public good

How

To integrate the AA Errors repository, we can:

1. Add the aa-errors repository as a dependency in our SDK
2. Implement a mechanism to query the repository in real-time when errors occur
3. Create a wrapper around our existing error handling to include the additional context from aa-errors
4. Update our documentation to reflect the new error handling capabilities
5. Contribute back to the aa-errors repository with any new errors we encounter
6. Consider creating a React hooks library to further enhance the developer experience with these errors
