FEATURE: Disable when CPU usage drops below threshold

[mkbg8]

I am using AMM to keep the machine awake when training some AI agents (if not awake, processing speed drops dramatically - and no, "Prevent automatic sleeping..." in macOS does not help). So, it would be fantastic for the tool to turn itself off when the CPU usage drops below a certain value (30% for example) as that would mean the computational phase has ended and there's no need for the machine to be kept awake.

Interesting idea! Feel free to make a contribution!
