Add function IsLockedTTLWithLimit checks if the key has been incremen…

[WanMuhafidzFaldi]

IsLockedTTLWithLimit checks if the key has been incremented more than the specified limit
within the given TTL. If the key is being created for the first time, it sets the TTL.
Example usage: check if a key has been incremented more than 10 times within 1 minute.

imo, better create general method IsLockedWithOption instead add new specific method for new feature.
enhance LockerOptions add new field Limit and set default value to 1 in constructor.

example:

Suggested change

	func (r *RedisLocker) IsLockedTTLWithLimit(key string, limit int, TTL time.Duration) bool {
	func (r *RedisLocker) IsLockedWithOption(key string, opts ...LockerOption) bool {
	conn := r.pool.Get()
	defer conn.Close()
	lockOpt := r.lockeroptions
	for _, opt := range opts {
	opt(&lockOpt)
	}
	lockKey := fmt.Sprintf("%s:%s", r.lockeroptions.Prefix, key)
	incr, err := redis.Int64(conn.Do("INCR", lockKey))
	if err != nil {
	return false
	}
	withLimit := lockOpt.Limit > 1
	if lockOpt.TTL > 0 && !(withLimit && incr == 1) {
	conn.Do("EXPIRE", lockKey, int(lockOpt.TTL.Seconds()))
	}
	return incr > int64(lockOpt.Limit)
	}

also applies to IsLockedTTL method
