The poller singleton code that I've been working on for over a year now is merged in. (Thanks Michael for expediting the final step).

This includes separate multi-frame states per bus and multiple poll lists as well as non-blocking one off queries. As well as more 'states'.

I have included some programming documentation in the change but am happy to supply more if needed. 

The ioniq 5 code has some examples of how it can be used. Some examples are:

* grabbing the vin as a one shot without blocking 

* having a short list of queries that are polled quickly for obd2ecu (this also demonstrates using a shorter frame break value and then a break after successful a response)

Have a play please!

Also interested in hearing what user tools might be worth looking at next for the poller object.
