Pull Request Overview

This PR implements support for preserving space in the decondenser formatting tool. The main purpose is to allow the formatter to maintain the original spacing from input while still providing the ability to control and constrain space sizes through configuration.

Key changes:

• Refactored space handling to support preserving input spacing with configurable size constraints
• Added new unescaping functionality with comprehensive escape sequence support
• Restructured the configuration system and removed the escape sequences feature
