Add bar

Hi everyone!

Please add "bar" as type of output information 😊 text like 2.11 GHz is norm, but is redundant -- most people (like me) just wan to see how "hard" their CPU is working.

In my system I'm using only bars for all parameters (left to right on picture): load (utilization), temperature, fan speed -- it takes up little space and very informative! I'd like to see CPU freq as 4th bar, but I can't 😕

P.S. Of course I could use genmon and custom script, but advice from README (about changing bar color) doesn't work for me so it's not a solution 😔
