Refactor printer functions into factory pattern

[bartveneman]

Summary

Refactored the CSS formatter to extract printer functions into a factory function (create_printers) that accepts configuration parameters. This enables code reuse and allows both minified and pretty-printed output without duplicating logic.

Key Changes

• Extracted create_printers factory function: Moved all printer functions (print_operator, print_list, print_value, etc.) into a factory that accepts formatting configuration (optional_space, newline, last_semicolon, minify flag, indent maker, and comment lookup function)
• Moved utility functions to module level: unquote() and print_string() are now exported at the module level since they don't depend on formatting configuration
• Created default printer exports: Instantiated create_printers with non-minified defaults (spaces, newlines, tab indentation) and exported all printer functions for direct use
• Simplified format() function: Now creates a printer instance with the appropriate configuration based on minify and tab_size options, then delegates to print_stylesheet
• Parameterized formatting variables: Replaced hardcoded OPTIONAL_SPACE, NEWLINE, and LAST_SEMICOLON constants with function parameters throughout the printer functions

Implementation Details

• The factory pattern allows the same printer logic to work with different formatting rules without conditional checks scattered throughout the code
• Comment lookup is now abstracted as a callback parameter, enabling the default exports to omit comments (since source CSS isn't available) while the format() function can provide comment extraction
• The make_indent function is parameterized to support both tab-based and space-based indentation based on configuration
