Increase blockDuration on next failed attempt

Hello, great library btw. I just wanna if it is possible to increase the blockDuration dynamically on succeeding failures?

Given this config

const loginLimiter = new RateLimiterRedis({
  redis: redisClient,
  keyPrefix: 'login:',
  points: 5, // 5 attempts
  duration: 60 * 60 * 24, // within a day
  blockDuration: 60, // 1 min
});

I want to set the next blockDuration to 5mins if the next rate limit reset was already consumed.

Just to illustrate:

5 attempts > fail > wait for 1 min > 1 min has passed > 5 attempts > fail > wait for 5mins

Is it possible for this library?

Thanks for the help.

@animir Hello Roman. I had the chance to try out your fibonacci block behavior. It works pretty well. Thanks dude!
