[REQUEST] Add command to probe running firmware?

[Hedda]

Suggest add unified command in zigpy-cli to probe running firmware in order to dump EmberZNet Ember config from bellows via EZSP.

$ bellows -d /dev/ttyUSB1 -b 115200 config --all

and

$ bellows -d /dev/ttyUSB1 -b 115200 info

Then such zigpy CLI command could possibly later be extended to offer similar information probe in other radio libraries for zigpy too?
