เพิ่มฟังก์ชั่นการตั้งค่า token ใน WiFiManager เราสามารถใช้พารามิเตอร์แบบกำหนดเองใน WiFiManager โดยเพิ่มโค้ดสำหรับการตั้งค่า token ในฟังก์ชั่น setup และใช้พารามิเตอร์ WiFiManager เพื่อตั้งค่า token ที่จะใช้ในการเชื่อมต่อกับ Blynk

ในโค้ดนี้ผมเพิ่มพารามิเตอร์แบบกำหนดเองสำหรับ token ของ Blynk โดยใช้ WiFiManagerParameter และเพิ่มพารามิเตอร์นี้ลงใน WiFiManager ในฟังก์ชั่น setup และบันทึก token จาก WiFiManager เพื่อใช้ในการเชื่อมต่อกับ Blynk
