API endpoint for on/off status of hub and/or shockers #280

It would be great to be able to see whether a shocker and/or hub is turned on or off in order to accurately estimate how many shockers would actually be usable when you have a database upon sending a command.

My use case:
I have a discord bot with a database of OpenShock users. The bot will shock them all at the same time when a secret trigger is tripped. The bot will also send a notification of how many people it shocked. Unfortunately, I can't accurately know how many shockers it actually triggered as I can't see if the ones I am sending a command to are on or off.
