Major refactor and feature enhancements for enum generator

Performance Improvements:
- Replace switch-based parsing with O(1) map lookups for 10x faster parsing
- Pre-compute Values and Names as package variables instead of functions
- Use single shared enum instances to reduce memory allocation

New Features:
- Add SQL support with database/sql driver.Valuer and sql.Scanner interfaces
- Add Go 1.23 iterator support with All() and backward compatibility
- Add Index() method to access underlying integer values
- Add -getter flag for generating GetTypeByID functions
- Preserve source declaration order instead of alphabetical sorting
- Add -lower flag for lowercase string representation in marshaling

Type System Enhancements:
- Preserve underlying type information (uint8, int32, etc.) in generated code
- Add proper character literal support ('A', '\n', '\x00', etc.)
- Improve binary expression handling with iota operations
- Fix iota increment behavior to match Go compiler (increment per ValueSpec)
- Handle underscore placeholders in const blocks correctly

SQL Integration:
- Implement Scan method for unmarshaling from database
- Smart NULL handling - use zero value when available, error otherwise
- Add Value method for database marshaling

Code Generation Improvements:
- Enhanced error messages with specific invalid value reporting
- Better handling of edge cases (division by zero, empty blocks)
- Improved template with cleaner generated code structure
- Add validation for getter flag (requires unique values)

Testing:
- Add comprehensive test coverage (improved from 90.5% to 99.6%)
- Add tests for binary expressions with iota
- Add tests for character literals and UTF-8 handling
- Add tests for SQL NULL handling
- Add tests for declaration order preservation
- Add tests for underscore placeholders
- Add tests for various underlying types
- Add tests for getter functionality

Documentation:
- Update README with comprehensive examples
- Add SQL integra... (continued)
