Bring back automatic device generation

[W-Floyd]

This used to be a thing ages ago (I had battery status, backlight, that come to mind). I want to redo this and extend it to more cases, such as:

• Hard Drives / Paritions (Overall size, space used, amount of data written/read, SMART data, etc.)
• Battery (Level, health, discharge rate)
• CPU stats (Model, usage, governor, power draw, per-core stats, cache, frequency, etc.)
• GPU stats (Model, usage, power, memory usage, frequency, etc.)
• Memory stats (Model, usage, power, etc.)
• Monitor controls (Laptop brightness, desktop monitor brightness via ddccontrol, DE color temperature controls integrated)

Ideally, we should not implement all of these things ourselves, and certainly not in this repo - if we need to, it might make sense to create an external library that may provide all of this information. I am sure this is something we can find elsewhere.
