Missing NMT broadcast

[JoostHendriks]

The send_nmt_command is expecting a state change for a single controller. In order to change the nmt state of all controllers in the network a broadcast can be used by sending 0 as node id. But there is no function in the library to do this.

Thanks for reporting the issue! To be clear, we should expect a state change message for all controllers?

Should we use a timeout to determine when all controllers should have responded?

[JoostHendriks]

Depends on the use case. If we use it before initiailization we don't know which controllers are connected yet (case I will be using it for). If we do, we can use the individual one. But there maybe are use cases on which you want to do a broadcast when the controllers are initialized. EMCY stop maybe?
