[Feature] Add a --query option to the CLI

[emileturcotte]

Hello,

Before anything, I'd like to say thank you to everyone who contributed, since this piece of software has immensely improved my XPS 15 battery life without the usual complexity, enabling me to work for much longer hours without charging.

I'm opening this feature request to propose a --query option on the CLI to enable users to obtain a specific value in plain text format. The use-cases I have for this is scripting and UI programming (custom widgets, for example). Autocomplete could be leveraged to provide the fields which can be queried.

This could look like :
Command : auto-cpufreq --query CPUAvg
Output : 42.67

If somebody has the time to quickly implement this (I assume it should be pretty straightforward to add), please go ahead; otherwise, I may do it myself in a couple of weeks/months, when I have more time ahead of me to dive into this project.

Glad to hear auto-cpufreq has helped you and that would indeed be an interesting feature to have.

Since I'm very limited with available time to do this myself and project is looking for contributors if you want to give it a try in implementing this functionality, please give it a try and contribute to the project and you will be credited for your work as part of future release.
