Enhancement: per-core historical CPU graphs in submenu

[nekohayo]

Description

As Astra Monitor is capable of low resource usage for monitoring, I would like to be able to use it as a replacement for gkrellm on my system, which looks like the screenshot below, for some cases where I want to monitor the history of CPU usage per core.

Currently, Astra Monitor only gives me history for all cores combined, or "current situation per core". I did not find something for this combination of the two, in the settings for the CPU "menu" section.

Environment

• Astra Monitor Version: 25 (EGOv42)
• GNOME Version: 46.x
• Operating System and Version: Fedora 40

We need continuous data mining for that. It's in the roadmap and eventually will be added. After that we can plan stuff like the one you asked for.
