Expose a way to determine if the rate limit is already hit?

If this exists already perhaps you can help me identify how to do it. I'm looking for a way to detect whether a particular key will overflow in the next call. Digging into the source it looks like it would be using this method
within_rate_limit? but would need to not increment the counter

def next_within_rate_limit?
      ExcessFlow::GlobalMutex.locked(lock_key: configuration.lock_key) do
        cleanup_stale_counters

        if current_requests < configuration.limit
          true
        else
          false
        end
      end
    end
end

The big difference is it wouldn't call the "bump_counter" method.

I was able to produce this behavior with something like this but would love to know if it's the recommended way.

    ExcessFlow.redis { |r| r.get(ExcessFlow::ThrottleConfiguration.new({ key: name.to_s, limit: rate, ttl: interval }).counter_key) }.to_i

Seems like a nice helper method would be a useful addition.
