Is your feature request related to a problem?

I have IOT devices that are only interested in certain kinds of events in their area. To reduce queue redundancy and data duplication, I'd prefer all events to be in the same queue, and handle the distribution with filtering.

Describe the solution you'd like

I would love it if BlazingMq could filter/route messages based on a circular or polygon geobounds

Alternatives you considered

The alternatives are:

1. over send data (not an option)
2. Introduce stream processors that splits streams for each IOT device, and creates separate queues/topics for those. The challenge with this approach is priorities are split across many queues/topics, with no way to gracefully prioritize different types of messages served by by different queues
