Feature Description

Some APIs like ctx.QueryBool or ctx.QueryFloat convert given variables. Why don't add APIs that let users convert the needed variable types?

For example, Query convertor API can be implemented like this (Since we can't use generics in methods):

func QueryFunc[T any](c *Ctx, key string, convertor func(string)(T, error), defaultValue ...T) (T, error)

Usage:

package main

import (
    "github.com/gofiber/fiber/v2"
    "github.com/google/uuid"
    "log"
)

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

	// [GET] /?id=01827964-1320-47b4-b2fa-c67fa9c39bed
	app.Get("/", func(c *fiber.Ctx) error {

		id, err := fiber.QueryFunc(c, "id", uuid.Parse)
       		if err != nil {
			log.Fatal(err)
			}

       		// some functionality
    })

    app.Listen(":3000")
}

We can implement other APIs like ctx.Params and ctx.Get functions.
