[REQUEST] Report per-core frequencies

[joe-mojo]

Is your feature request related to a problem? Please describe.
The CPU graph reports only one global frequency. htop is able to show the specific frequency for each core.

Describe the solution you'd like
Enlarge a little bit the per-core window and add the cpu frequency at the end of each core graph (before or after the core temperature)

Describe alternatives you've considered
Using htop.

Additional context
I'm a geek.
