Explicit parenthesis around exponent values

[suleman-uzair]

This PR updates Parslet parsing and transformation rules and the conversion methods.

closes #46

[Copilot]

Pull Request Overview

This PR implements explicit parenthesis around exponent values in Parslet parsing and transformation rules, replacing string-based exponent handling with a new Number class. The changes introduce structured handling of power numerators by wrapping exponent values in a Number object, updating conversion methods to support the new structure, and modifying test expectations to align with the new data structures.

• Introduces a new Number class to handle exponent values with proper conversion methods
• Updates Unit, Dimension, and other classes to use Number objects for power_numerator instead of strings
• Modifies parsing rules to structure exponent values as power_numerator objects with explicit parenthesis support

[nitpick] These bridge methods in the Fenced class create tight coupling with the Number class. Consider using composition patterns or mixins to avoid duplicating Number's interface methods.

• Magic string 'unknown' is used directly. This should use the UNKNOWN constant defined at line 47 for consistency.
