EFStyle25DParams

public class EFStyle25DParams : EFStyleParams

Parameters for 2.5D QR code styling.

This class defines the styling parameters for 2.5D QR codes, which create a three-dimensional appearance using shading and depth effects. The 2.5D style simulates depth by using different colors for the top, left, and right faces of each module.

## Features

Three-dimensional appearance with depth simulation
Customizable height for data and position modules
Multi-color shading (top, left, right faces)
Icon and backdrop support
Realistic 3D visual effect

## Usage

 let params = EFStyle25DParams(
     icon: icon,
     backdrop: backdrop,
     dataHeight: 1.0,
     positionHeight: 1.0,
     topColor: .black,
     leftColor: .darkGray,
     rightColor: .lightGray
 )

 let style = EFQRCodeStyle.style25D(params)

## Visual Characteristics

Modules appear to have depth and volume
Different colors create shading effects
Height parameters control the 3D appearance
Creates a modern, sophisticated look
