hyprexpo: crash on setting colum count 1

[icy-comet]

I was just playing around the config and set columns = 1 hoping for a vertical layout or something, and Hyprland froze. On multiple invocations, it crashed.

I don't know if this is not supposed to work at all. But at least the docs/readme should mention so or it should send out a warning.

columns 1 makes no sense, we should block it probably
