EFQRCodeStyleFunction

public class EFQRCodeStyleFunction : EFQRCodeStyleBase

Function-based QR code implementation.

This class implements the function-based QR code rendering, creating QR codes with mathematical functions that determine the appearance of data modules.

## Features

• Mathematical function-based data module generation
• Dynamic patterns using fade and circle functions
• Position detection pattern styling
• Icon and backdrop support

## Usage

 let params = EFStyleFunctionParams(
     position: position,
     data: dataParams
 )

 let style = EFQRCodeStyleFunction(params: params)
