feat: Add account event parser and protocol type definitions

- Add account event parser (account_event_parser.rs) for account-level event handling
- Introduce type definitions for pumpfun, pumpswap, raydium_amm_v4, raydium_clmm, raydium_cpmm protocols
- Enhance event processor to support account event processing alongside transactions
- Improve subscription system with separate transaction and account filters
- Optimize parser configuration using Option types for cleaner code structure
- Update examples and documentation to reflect new capabilities

Changes include:
- 6 new types.rs files for protocol-specific data structures
- Updated event processor for account, transaction, and block meta events
- Refactored subscription manager with account filtering support
- Enhanced metrics and batch processing logic
