EFQRCodeStyle25D

public class EFQRCodeStyle25D : EFQRCodeStyleBase

2.5D QR code implementation.

This class implements the 2.5D QR code rendering, creating QR codes with a three-dimensional appearance using shading and depth effects. The 2.5D style simulates depth by rendering each module with multiple faces using different colors.

## Features

• Three-dimensional appearance with depth simulation
• Multi-color shading for realistic 3D effect
• Customizable height for different module types
• Icon and backdrop support
• Sophisticated visual appearance

## Usage

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

 let style = EFQRCodeStyle25D(params: params)
