Request: optional JSON output for commands

[ladydascalie]

Hi!
Thanks for this amazing project.

I would like to inquire about the possibility of adding an optional json output mode to commands like list, info, battery etc.

I believe this would help a lot especially in automating / writing simple gui tools around dualsensectl.

If there's interest in this, I'm not against giving it a shot myself, but I don't want to step on anyone's toes if this isn't a desirable goal for this project.

I think that would be nice to have, patches welcome!

I have started some exploratory work in #26 for this issue.
