🐛 Can't register a custom converter

[sebastiannm]

Fiber version
2.19.0

Issue description
Hi, I'm using the Mongodb Driver and when using QueryParser, I get an error saying that the type "primitive.ObjectID" is unknown. This is not specific to Fiber because others frameworks have the same problem, but other frameworks allow to register a custom Converter to fix the issue.
Ex: https://githubmemory.com/repo/kataras/iris/issues/1671

But in fiber, schema is inside internal, so I can't use it from my code

Code snippet

package main

import (
"github.com/gofiber/fiber/v2"
"github.com/gofiber/fiber/v2/internal/schema"
"go.mongodb.org/mongo-driver/bson/primitive"
)

func main() {
  app := fiber.New()

 schema.NewDecoder().RegisterConverter(primitive.ObjectID{}, func(value string) reflect.Value {
		id, err := primitive.ObjectIDFromHex(value)
		fmt.Println("id", id)
		if err != nil {
			return reflect.Value{}
		}
		return reflect.ValueOf(id)
  })

  log.Fatal(app.Listen(":3000"))
}
