Resize: Opposite of Smart

[wesbos]

Adding resizing shortcuts, I really like the smart resize option that will pick width or height depending on layout:

Finding myself with 4 commands for small/large smart resizes.

up = 'resize smart +70'
shift-up = 'resize smart +20'
down = 'resize smart -70'
shift-down = 'resize smart -20'

Now I want to add the same commands for the opposite of whatever smart is.

I could explicitly add 8 more keyboard commands for width/height, but what I really want is something that would just smart resize the opposite axis like this:

cmd-down = 'resize !smart -20'

This might be a dumb request so feel free to close, but I'm finding myself making (and remembering) a million shortcuts

I don't mind adding smart-opposite if anyone wants to bring a PR, should be easy to implement
