Battery charging manager

CLI for managing the battery charging status for M1 Macs. Can be used to enable/disable the Macbook from charging the battery when plugged into power.

The idea is to make it possible to keep a chronically plugged in Macbook at for example 80% battery, since that will prolong the longevity of the battery.

After running battery charging off you can verify the change visually by looking at the battery icon:

After running battery charging on you will see it change to this:
