Feature Request: Choose label slot for "Run Command" output

[jonseitz]

I'm using the "Run Command" action to display data from different scripts (i.e. my unread email count from notmuch) on my stream deck. I'd like to be able to display those in either the top or bottom label positions, to match how I've set up some other buttons.

I'm happy to poke around at the code and put together a pull request if you're open to it. Based on a quick look, it looks like we'd need to add an additional config row to choose one of the three label positions, then when self.set_center_label(result) is called we'd just need to add some logic to call the method for the appropriate position. Does that seem reasonable?
