CPU Frequency values seem to favor unused cpu than actively used ones

### What Happened?

When installing the app, the values that were being shown for frequency didn't look right since my cpu runs hot due to it being constantly overclocked.

The average value being shown was around `0.6-0.9GHz` when most other metrics clock it multiples higher than that.

Some ideas on how to fix this is to:
- average the frequency among threads
- average the frequency among actively used threads (currently using this locally)
- fetch the max value

### Steps to Reproduce

1. Compiled from GitHub
2. Run

### Expected Behavior

The app to show something closer to what other monitors show. My bios and windows show readings much higher.

### OS Version

Other Linux

### OS Architecture

amd64 (on most hardwares)

### Session Type

Secure Session (Wayland)

### Software Version

Compiled from git
