LuminousIntensity class

Represents a quantity of luminous intensity.

Luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI base unit for luminous intensity is the Candela (cd).

This class provides a type-safe way to handle luminous intensity values and conversions between different units (e.g., candelas, millicandelas).
