Add option to ignore drives in standby

[slaecker]

I want to regularly parse openSeaChest output and get it scraped by Prometheus via node-exporter. But I don't want to wake the device everytime the script is running openSeaChest. smartctl supports the -n standby option to skip any device which is currently in standby. Can you please implement such an option in openSeaChest?

@slaecker,

This is a good idea! We can work on implementing this.

Are you only looking to skip drives in standby? Or the other power modes as well like smartctl's -n option allows?

I personally only care for standby but I guess if you are already on it, it makes sense to implement options to ignore other power states as well. This will make the whole thing more feature complete.
