[BUG]bpytop misbehaves after CPU cores are disabled and crashes after they are enabled

[linuxcf]

Describe the bug

[A clear and concise description of what the bug is.]

To Reproduce

[Steps to reproduce the behavior:]

1. (While bpytop is running, disable some CPU cores, e.g. sudo chcpu -d 2-11 (here I disable cores 2-11). This will result in weird numbering of the CPU cores on the bpytop display.
2. In the above example, with cores 2-11 still disabled, shut down bpytop and restart it. Now, the active cores are shown properly.
3. Now re-enable the deactivated cores (sudo chcpu -e 2-11), while bpytop is running from step (2) above.. bpytop will now crash.

Expected behavior

[A clear and concise description of what you expected to happen.] The displayed cores should correspond to the active ones. For example, in the classic top if a core is deactivated, it is no longer shown. In htop it is explicitly shown as off-line. bpytop should not crash if more cpu cores are enabled.
