Add min/max allowed frequencies option (#309) (#324) 

* Add min/max allowed frequencies option (#309)

Setting the minimum/maximum allowed CPU frequencies is now possible
via 'scaling_min_freq' and 'scaling_max_freq' options in config
for both modes (charger and battery).
Values should be given in kHZ.

Example:
scaling_min_freq = 1800000
scaling_max_freq = 2000000

I also did autoformatting via 'black', using --line-length 100.
Code is now a bit tidier than before.

* Fixes for min/max allowed frequencies option

* Further modify min/max frequency option

* Fix temporary modification in min/max allowed frequency option
