How to process requests evenly with RateLimiterQueue?
I'm sending requests to a heavily rate-limited service but want them all to get through eventually, so I have a RateLimiterQueue with the default maximum size, wrapping a RateLimiterMySQL which is using the Sequelize backend for MySQL.

The issue is that whilst we have configured the service to have 10 points per hour, only 5 requests are being executed per hour.

I have the limiter set with the following config (as well as database specific config):

```json
{
  "duration": 3600,
  "points": 10,
  "execEvenly": true
}
```

And the queue wrapping the limiter has no additional configuration. Is this a known issue?

**EDIT**: use an example from [Consume points evenly](https://github.com/animir/node-rate-limiter-flexible/wiki/Consume-points-evenly) article. At the time of this edit, `execEvenly` option doesn't work with RateLimiterQueue.
