switch-preset-column-width but backwards

[arm32x]

As far as I can tell, the switch-preset-column-width and switch-preset-window-height actions can only cycle forwards through presets. I have a decent number of presets configured, so it would be nice to have a second keybind to cycle backwards through them to access the one I want quicker.

I guess some kind of switch-backward-preset-column-width (name suggestions welcome) would be alright and relatively straightforward.
