Battery-poly not understanding the "Not charging" status

[kuon]

The battery-poly blocklet is crashing on my system (HP laptop) when there is power, but not enough to charge the system.

The status reported by the kernerl is Not charging.

I think it should be handled here:

i3blocks-contrib/battery-poly/battery-poly

Line 101 in 9d66d81

if raw_status == "Unknown" or raw_status == "Full":

With or raw_status == "Not charging" added.

I can create a PR but this seem minor enough.
