Improve error handling and logging in message processing

- Updated HandleMessage function to include the actual message content in error notices for invalid messages, enhancing clarity for debugging.
- Added nil check in Value method of tag encoder to prevent potential nil pointer dereference.
- Refactored tag handling in spider to utilize hex-encoded pubkeys for improved compatibility and clarity in filter creation.
- bump to v0.19.10
