New Flag Types:

StringArray - Allows flags to be specified multiple times (e.g., --tag foo --tag bar)
Choice - Restricts values to a predefined set (e.g., environment must be "dev", "staging", or "production")
Range - Validates numeric values within a specific range (e.g., port must be between 1024-65535)
File - Validates that the value is an existing file path
Directory - Validates that the value is an existing directory path

Flag Constraint System:

RequiredIf - A flag becomes required when another flag is set
ConflictsWith - Flags that are mutually exclusive
Requires - A flag that requires other flags to be set

Key Features:

Validation happens during flag parsing for immediate feedback
Enhanced error messages clearly explain validation failures
Help system automatically displays constraints (Choice shows options, Range shows min-max)
Comprehensive test coverage for all new features
Created advanced_flags_demo.rs example showcasing all features
