Generic rate limit by key using sliding window algorithm. See Cloudflare blog for details: https://blog.cloudflare.com/counting-things-a-lot-of-different-things/

## Example

```golang

package main

import (

	"fmt"

	"log"

	"time"

	"github.com/Snawoot/rlzone"

)

func main() {

	rl, err := rlzone.NewSmallest[string](1*time.Minute, 5)

	if err != nil {

		log.Fatalf("unable to create ratelimit instance: %v", err)

	}

	for i := 0; i < 6; i++ {

		fmt.Println(rl.Allow("user1"))

	}

	fmt.Println(rl.Allow("user2"))

	// Output:

	// true

	// true

	// true

	// true

	// true

	// false

	// true

}
